Chapter 5.10, Problem 30CCR

To determine

To find: The solution of the expression ${\left(xz\right)}^2$ if $x=2$ , $y=-3$ , and $z=4$ .

Answer to Problem 30CCR

The solution of the expression ${\left(xz\right)}^2$ for $x=2$ and $z=4$ is $64$ .

Explanation of Solution

Given information:

The given expression is ${\left(xz\right)}^2$ .

Calculation:

To find the solution of the expression for $x=2$ and $z=4$ , substitute 2 for $x$ and 4 for $z$ in the expression.

  $\begin{array}{c}{\left(2\cdot 4\right)}^2=8^2\\ =64\end{array}$

Therefore, thesolution of the expression ${\left(xz\right)}^2$ for $x=2$ and $z=4$ is $64$ .
