$$

Answer to Problem 1E

Solution: The expressions $2^3$ and $3^2$ are not equal.

Explanation of Solution

Explanation:Given: The expressions $2^3$ and $3^2$ .

Calculation: We have been given the expressions $2^3$ and $3^2$ . Let us find the values of these expressions and see whether they are equal or not.

  $\begin{array}{l}{2}^3=2\times 2\times 2=8\\ 3^2=3\times 3=9\end{array}$

Since $8\ne 9$ , hence the expressions $2^3$ and $3^2$ are not equal.

Conclusion: The expressions $2^3$ and $3^2$ are not equal.
