Chapter 4.1, Problem 17WE

To determine

To state: The expression $r\cdot \left(-4\right)\cdot s\cdot s$ in exponential form.

Answer to Problem 17WE

The required exponential form is $-4r{s}^2$ .

Explanation of Solution

Given information:

The given expression $r\cdot \left(-4\right)\cdot s\cdot s$

Calculation:

  $\begin{array}{l}=r\cdot \left(-4\right)\cdot s\cdot s\\ =-4\cdot r\cdot \left(s\cdot s\right)\end{array}$

(Group the constant and variables)

  $=-4r{s}^2$

The required exponential form is $-4r{s}^2$ .
