Introduction

In mathematics, particularly in algebra and arithmetic, we often encounter expressions that involve fractions and exponents. One common operation is squaring a fraction, which can be a bit tricky to handle. In this article, we will explore the concept of squaring a fraction and determine which of the following expressions is equal to (3/5N)^2.

Understanding the Concept of Squaring a Fraction

To square a fraction, we need to multiply the fraction by itself. This means that we will multiply the numerator by itself and the denominator by itself. In the case of (3/5N)^2, we will multiply 3 by 3 and 5N by 5N.

Squaring the Numerator and Denominator

When we square the numerator, we get:

3^2 = 9

When we square the denominator, we get:

(5N)^2 = 25N^2

Simplifying the Expression

Now that we have squared the numerator and denominator, we can simplify the expression by dividing the squared numerator by the squared denominator:

(3/5N)^2 = 9 / 25N^2

Analyzing the Options

Let's assume we have the following options:

A. 9 / 25N B. 9 / 25N^2 C. 9N / 25 D. 9N^2 / 25

Which Option is Equal to (3/5N)^2?

To determine which option is equal to (3/5N)^2, we need to compare each option with the simplified expression we obtained earlier:

9 / 25N^2

Option A: 9 / 25N

This option is not equal to (3/5N)^2 because the denominator is missing the squared term (N^2).

Option B: 9 / 25N^2

This option is equal to (3/5N)^2 because it matches the simplified expression we obtained earlier.

Option C: 9N / 25

This option is not equal to (3/5N)^2 because the numerator is missing the squared term (N^2).

Option D: 9N^2 / 25

This option is not equal to (3/5N)^2 because the denominator is missing the squared term (N^2).

Conclusion

Based on our analysis, we can conclude that the correct option is:

B. 9 / 25N^2

This option is equal to (3/5N)^2 because it matches the simplified expression we obtained earlier.

Introduction

In our previous article, we explored the concept of squaring a fraction and determined which of the following expressions is equal to (3/5N)^2. In this article, we will answer some frequently asked questions related to squaring a fraction.

Q&A

Q: What is the concept of squaring a fraction?

A: Squaring a fraction involves multiplying the fraction by itself. This means that we will multiply the numerator by itself and the denominator by itself.

Q: How do we square a fraction?

A: To square a fraction, we multiply the numerator by itself and the denominator by itself. For example, to square the fraction 3/5, we would multiply 3 by 3 and 5 by 5.

Q: What is the simplified expression for (3/5N)^2?

A: The simplified expression for (3/5N)^2 is 9 / 25N^2.

Q: Can we square a fraction with a variable in the denominator?

A: Yes, we can square a fraction with a variable in the denominator. For example, to square the fraction 3/(2x), we would multiply 3 by 3 and (2x) by (2x).

Q: How do we handle exponents when squaring a fraction?

A: When squaring a fraction, we need to handle exponents carefully. For example, if we have the fraction 2^3 / 3^2, we would square the numerator and denominator separately: (2³⁾2 / (3²⁾2 = 2^6 / 3^4.

Q: Can we square a fraction with a negative exponent?

A: Yes, we can square a fraction with a negative exponent. For example, to square the fraction 2^-3 / 3^2, we would multiply 2^-3 by 2^-3 and 3^2 by 3^2.

Q: How do we simplify a fraction after squaring it?

A: To simplify a fraction after squaring it, we need to look for any common factors between the numerator and denominator. For example, if we have the fraction 9 / 25N^2, we can simplify it by dividing both the numerator and denominator by 9.

Q: Can we square a fraction with a complex number in the denominator?

A: Yes, we can square a fraction with a complex number in the denominator. For example, to square the fraction 3 / (2 + 3i), we would multiply 3 by 3 and (2 + 3i) by (2 + 3i).

Conclusion

In this article, we answered some frequently asked questions related to squaring a fraction. We covered topics such as squaring a fraction with a variable in the denominator, handling exponents, and simplifying a fraction after squaring it.

Final Thoughts

Squaring a fraction can be a bit tricky, but with practice and patience, you can master this concept. Remember to always multiply the numerator by itself and the denominator by itself, and then simplify the resulting expression.
