The expression \( 4^3 \) can be calculated as follows:
\[ 4^3 = 4 \times 4 \times 4 \]
Calculating this step-by-step:
- First, compute \( 4 \times 4 = 16 \).
- Then, multiply that result by \( 4 \): \[ 16 \times 4 = 64 \]
Therefore, \( 4^3 = 64 \).
So, the expression equivalent to \( 4^3 \) is \( 64 \).
