Chapter 11.1, Problem 49CCR

To determine

To find: Evaluate each expression.

Answer to Problem 49CCR

  $y^{2}z=96$

Explanation of Solution

Given information:

  $y^{2}z$

  $\begin{array}{l}y=-4\\ z=6\end{array}$

  $y^{2}z$

On substituting

  $\begin{array}{l}y=-4\\ z=6\end{array}$

On solving

We get

  $\begin{array}{l}{y}^{2}z={\left(-4\right)}^2\times 6\\ \Rightarrow y^{2}z=16\times 6\\ \Rightarrow y^{2}z=96\end{array}$

Therefore,

  $y^{2}z=96$
