Chapter 4.2, Problem 47HP

To determine

To write : the fraction that represent one piece of the pizza and write the fraction as a power that has negative exponent.

Answer to Problem 47HP

The fraction that represent one piece of the pizza is $\frac{1}{25}$ and write the fraction as a power that has negative exponent is $5^{-2}$

Explanation of Solution

Given information :

A pizza is cut into 25 equal piece

A pizza is cut into 25 equal piece

Therefore,one slice of pizza is represented as a fraction $\frac{1}{25}$

The fraction $\frac{1}{25}$ can also be writtenas a power $\frac{1}{5^2}$

The fraction as a power that has negative exponent is

  $\begin{array}{l}\frac{1}{5^2}\\ 5^{-2}\end{array}$

Hence, thefraction that represent one piece of the pizza is $\frac{1}{25}$ and write the fraction as a power that has negative exponent is $5^{-2}$
