5 to the 3rd power, written as 53, equals 125. This is calculated by multiplying 5 by itself two more times, which can be expressed as:
5 × 5 × 5 = 25 × 5 = 125.
In more detail, when you raise a number to a power, you are performing repeated multiplication. In this case, the base number is 5 and the exponent is 3, indicating that we should multiply 5 three times. Therefore, the final result is 125.
