In the realm of mathematics, simplification is a fundamental skill that allows us to express complex expressions in a more concise and manageable form. This skill is particularly crucial when dealing with exponents and fractions. In this comprehensive guide, we will delve into the process of simplifying the expression (1/6)³, providing a step-by-step breakdown and exploring the underlying mathematical principles.

Understanding Exponents and Fractions

Before we embark on the simplification journey, let's lay a solid foundation by revisiting the concepts of exponents and fractions. An exponent indicates the number of times a base number is multiplied by itself. For instance, in the expression x^n, x represents the base, and n represents the exponent. This means that x is multiplied by itself n times (x * x * ... * x, n times). Fractions, on the other hand, represent a part of a whole, expressed as a ratio of two numbers, the numerator and the denominator. The numerator indicates the number of parts we have, while the denominator indicates the total number of parts the whole is divided into.

In our target expression, (1/6)³, we encounter both an exponent and a fraction. The base is the fraction 1/6, and the exponent is 3. This signifies that we need to multiply the fraction 1/6 by itself three times.

Step-by-Step Simplification of (1/6)³

Now that we have a firm grasp of the underlying concepts, let's proceed with the step-by-step simplification of (1/6)³:

  1. Expand the expression:

The first step involves expanding the expression to explicitly show the repeated multiplication:

(1/6)³ = (1/6) * (1/6) * (1/6)

This expansion clarifies the operation we need to perform – multiplying the fraction 1/6 by itself three times.

  1. Multiply the numerators:

When multiplying fractions, we multiply the numerators together to obtain the numerator of the resulting fraction:

1 * 1 * 1 = 1

This step demonstrates the straightforward multiplication of the numerators, resulting in 1 as the numerator of the simplified fraction.

  1. Multiply the denominators:

Similarly, we multiply the denominators together to obtain the denominator of the resulting fraction:

6 * 6 * 6 = 216

This step showcases the multiplication of the denominators, yielding 216 as the denominator of the simplified fraction.

  1. Combine the results:

Finally, we combine the results from steps 2 and 3 to form the simplified fraction:

(1/6)³ = 1/216

This final step presents the simplified form of the expression, 1/216, which represents the result of multiplying 1/6 by itself three times.

Alternative Approach: Distributing the Exponent

Another approach to simplifying (1/6)³ involves distributing the exponent to both the numerator and the denominator of the fraction. This method leverages the property that (a/b)^n = a^n / b^n. Let's apply this property to our expression:

(1/6)³ = 1³ / 6³

Now, we simply calculate 1³ and 6³:

1³ = 1 * 1 * 1 = 1

6³ = 6 * 6 * 6 = 216

Substituting these values back into our expression, we get:

(1/6)³ = 1/216

This alternative approach yields the same simplified fraction, 1/216, demonstrating the flexibility and consistency of mathematical principles.

Conclusion: Mastering Simplification

In this comprehensive guide, we have successfully simplified the expression (1/6)³ using two distinct approaches. Both methods led us to the same simplified fraction, 1/216, reinforcing the fundamental principles of exponents and fractions. Simplification is a crucial skill in mathematics, enabling us to express complex expressions in a more manageable form. By mastering this skill, we gain a deeper understanding of mathematical concepts and enhance our problem-solving abilities. Remember to practice regularly and explore various simplification techniques to solidify your understanding and build confidence in your mathematical journey. Whether you choose to expand the expression directly or distribute the exponent, the key is to apply the fundamental principles correctly and systematically. With consistent practice, you'll become a simplification pro!

This is particularly important when dealing with exponents and fractions. This article will provide a step-by-step guide to simplifying the expression (1/6)³, exploring the mathematical principles involved, and highlighting the significance of simplification in mathematics.

Laying the Foundation: Understanding Exponents and Fractions

Before diving into the simplification process, let's revisit the fundamental concepts of exponents and fractions. Exponents represent repeated multiplication. In the expression x^n, 'x' is the base, and 'n' is the exponent. This means 'x' is multiplied by itself 'n' times (x * x * ... * x, 'n' times). Fractions represent a part of a whole, expressed as a ratio of two numbers: the numerator and the denominator. The numerator indicates the number of parts we have, while the denominator indicates the total number of parts the whole is divided into.

In the expression (1/6)³, we encounter both exponents and fractions. The base is the fraction 1/6, and the exponent is 3. This signifies that we need to multiply the fraction 1/6 by itself three times. Understanding these core concepts is crucial for successful simplification.

The Journey to Simplification: A Step-by-Step Approach

Now, let's embark on the simplification journey for (1/6)³ using a detailed step-by-step approach:

  1. Expanding the Expression: The initial step involves expanding the expression to explicitly show the repeated multiplication:

    (1/6)³ = (1/6) * (1/6) * (1/6)

    This expansion makes it clear that we need to multiply the fraction 1/6 by itself three times. This is a visual and conceptual aid, making the process easier to grasp.

  2. Multiplying the Numerators: When multiplying fractions, we multiply the numerators together to get the numerator of the resulting fraction:

    1 * 1 * 1 = 1

    The numerators are multiplied straightforwardly, resulting in 1 as the numerator of the simplified fraction. This demonstrates a fundamental rule of fraction multiplication.

  3. Multiplying the Denominators: Similarly, we multiply the denominators together to obtain the denominator of the resulting fraction:

    6 * 6 * 6 = 216

    This step showcases the multiplication of the denominators, yielding 216 as the denominator of the simplified fraction. This is another core element of fraction multiplication.

  4. Combining the Results: Finally, we combine the results from steps 2 and 3 to form the simplified fraction:

    (1/6)³ = 1/216

    This final step presents the simplified form of the expression: 1/216. This is the result of multiplying 1/6 by itself three times, now expressed in its simplest fractional form.

An Alternative Path: Distributing the Exponent

Another way to simplify (1/6)³ is by distributing the exponent to both the numerator and the denominator of the fraction. This method uses the property that (a/b)^n = a^n / b^n. Let's apply this to our expression:

(1/6)³ = 1³ / 6³

Now, we calculate 1³ and 6³:

1³ = 1 * 1 * 1 = 1

6³ = 6 * 6 * 6 = 216

Substituting these values back into our expression, we get:

(1/6)³ = 1/216

This alternative method leads to the same simplified fraction, 1/216, showing the flexibility and consistency of mathematical principles. It offers a different perspective on simplification, reinforcing the understanding of exponent properties.
