Introduction

In mathematics, monomials are algebraic expressions consisting of a single term, which can be a constant, a variable, or a combination of variables and constants. Simplifying monomials is an essential skill in algebra, as it helps to reduce complex expressions into their simplest form. In this article, we will focus on simplifying the given monomial: $\left(-\frac{4 p q^5 r^3}{8 p^2 q^2 r^{10}}\right)^2$ . We will break down the process into manageable steps, using mathematical concepts and techniques to simplify the expression.

Understanding the Monomial

Before we begin simplifying the monomial, let's first understand its structure. The given expression is a fraction, where the numerator is $-4 p q^5 r^3$ and the denominator is $8 p^2 q^2 r^{10}$ . The expression is raised to the power of 2, indicating that we need to square the fraction.

Squaring a Fraction

When we square a fraction, we need to square both the numerator and the denominator separately. This means that we will multiply the numerator by itself and the denominator by itself.

Step 1: Square the Numerator

To square the numerator, we need to multiply $-4 p q^5 r^3$ by itself.

\left(-4 p q^5 r^3\right)^2 = (-4)^2 \cdot (p)^2 \cdot (q^5)^2 \cdot (r^3)^2

Using the exponent rules, we can simplify the expression further.

(-4)^2 = 16

(p)^2 = p^2

(q^5)^2 = q^{10}

(r^3)^2 = r^6

So, the squared numerator becomes:

16 p^2 q^{10} r^6

Step 2: Square the Denominator

To square the denominator, we need to multiply $8 p^2 q^2 r^{10}$ by itself.

\left(8 p^2 q^2 r^{10}\right)^2 = (8)^2 \cdot (p^2)^2 \cdot (q^2)^2 \cdot (r^{10})^2

Using the exponent rules, we can simplify the expression further.

(8)^2 = 64

(p^2)^2 = p^4

(q^2)^2 = q^4

(r^{10})^2 = r^{20}

So, the squared denominator becomes:

64 p^4 q^4 r^{20}

Step 3: Simplify the Expression

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

\frac{16 p^2 q^{10} r^6}{64 p^4 q^4 r^{20}}

We can simplify the expression further by canceling out common factors.

\frac{16}{64} \cdot \frac{p^2}{p^4} \cdot \frac{q^{10}}{q^4} \cdot \frac{r^6}{r^{20}}

Using the exponent rules, we can simplify the expression further.

\frac{1}{4} \cdot p^{-2} \cdot q^6 \cdot r^{-14}

So, the simplified expression becomes:

\frac{q^6 r^{-14}}{4 p^2}

Conclusion

Simplifying the given monomial requires us to square both the numerator and the denominator, and then simplify the resulting expression by canceling out common factors. By following the steps outlined in this article, we can simplify the expression and arrive at the final answer.

Key Takeaways

Squaring a fraction involves squaring both the numerator and the denominator separately.

Final Answer

The final answer is: $\boxed{\frac{q^6 r^{-14}}{4 p^2}}$
