Power of 4 Calculator
Definition – What is the “4th Power” of a number?
The “4th Power” of a number is the number multiplied by itself four times.
Write it with a raised number 4 (the exponent) next to the base number. “number4“or “54” or “84” are examples of using an exponent 4.
Saying “3 to the power of 4” or 34 is the same as saying 3 times 3 times 3 times 3 (equals 81).
Saying “20 to the exponent 4” or 204 is the same as saying 20 x 20 x 20 x 20 (equals 16,000).
To find a number to a different power, use our simple exponent calculator. To find the number needed to find the exponent 4 of a number, use the 4th root.
Formula – How to Calculate the 4th power of a number
The exponent 4 of a number is found by multiplying that number by itself 4 times.
number4 = number x number x number x number
To do the opposite, use our 4th root calculator.
Example
14 = 1 times 1 times 1 times 1 = 1
24 = 2 x 2 x 2 x 2 = 16
34 = 3 x 3 x 3 x 3 = 81
44 = 4 times 4 times 4 times 4 = 256
54 = 5 times 5 times 5 times 5 = 625
