Final answer:
To evaluate 5^3, multiply the base (5) by itself three times to get 5 x 5 x 5, which equals 125, matching option A.
Step-by-step explanation:
To evaluate the expression 5^3, we simply multiply the base, which is 5, by itself three times. The exponent 3 tells us the number of times to multiply the base by itself. Therefore, 5^3 is equivalent to 5 × 5 × 5.
Performing the multiplication:
So, 5^3 equals 125, which corresponds to option A.
