Evaluating $2^3$ and $3^2$

When evaluating an exponential expression with a numerical base, the base is multiplied by itself the number of times indicated by the exponent. For example, to evaluate $2^3$ , the base $2$ is multiplied by itself three times ( $2 \cdot 2 \cdot 2$ ) to give $8$ . Similarly, evaluating $3^2$ involves multiplying the base $3$ by itself two times ( $3 \cdot 3$ ) to yield $9$ . This demonstrates how exponential notation is expanded to calculate a final numerical value.
