Chapter SH, Problem 9.4.4EP

To determine

To find: Given expression using a positive exponent.

Answer to Problem 9.4.4EP

Given expression in positive exponent is $\frac{1}{2^7}$ .

Explanation of Solution

Given information:

  $2^{-7}$

Calculation:

The given expression is $2^{-7}$ .

According to the negative exponent definition, $a^{-n}=\frac{1}{a^n}$ where $n$ is a whole number.

  $\begin{array}{l}=2^{-7}\\ =\frac{1}{2^7}\end{array}$

Thus, given expression in positive exponent is $\frac{1}{2^7}$ .
