Chapter 7: Q9. (page 430)

Simplify each expression. Assume that no denominator equals 0.
$\frac{p^{4} t^{- 2}}{r^{- 5}}$

Short Answer

Expert verified

The required expression is represented by $\frac{p^{4} r^{5}}{t^{2}}$ .

Step by step solution

Step 1. Determine the identity that can be used.

The identity represented by $a^{- n} = \frac{1}{a^{n}}$ will convert the negative exponents into positive.

Step 2. Use the obtained identity.

Take the help of the identity $a^{- n} = \frac{1}{a^{n}}$ for the negative exponents.

$\frac{p^{4} r^{5}}{t^{2}}$

Step 3. Write the conclusion.

The obtained expression is $\frac{p^{4} r^{5}}{t^{2}}$ which cannot be simplified further so it’s the required simplification.
