Chapter 4.2, Problem 26IP

To determine

To write : the expression using a negative exponent other than $-1$ .

Answer to Problem 26IP

The expression using a negative exponent is $2^{-2}$ .

Explanation of Solution

Given information :

Consider, the expression is,

  $\frac{1}{4}$

The value of expression is:

  $\begin{array}{l}\frac{1}{4}\\ \frac{1}{2^2}\\ 2^{-2}\left[\text{definition of negative exponent}\right]\end{array}$

Hence, the expression using a negative exponent is $2^{-2}$ .
