Understanding Exponentiation

Exponentiation is a mathematical operation that involves raising a number to a power. The general form of exponentiation is $a^b$ , where $a$ is the base and $b$ is the exponent. The result of $a^b$ is obtained by multiplying $a$ by itself $b$ times. For example, $2^3 = 2 \times 2 \times 2 = 8$ .

Evaluating $4^3$

To evaluate $4^3$ , we need to multiply 4 by itself 3 times. This can be done using the following calculation:

$4^3 = 4 \times 4 \times 4 = 64$
