# 4th Power

LAST UPDATE: October 21st, 2020

## 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

## What is “to the power of 4”?

A number to the power of 4 is the number times itself 4 times. 3 to the power of 4 is 3 x 3 x 3 x 3 (81). 10 to the power of 4 is 10 x 10 x 10 x 10 (10,000).

## How do you solve for a number to the exponent 4?

Multiply the number by itself 4 times over.

## How do you type an exponent 4?

To type an exponent in a word processor, look for the “superscript” command (it is usually near commands such as bold or italic).
To type an exponent for the web, use the markup. It is an HTML tag that surrounds the exponent.

## What is the difference between “4th Power,” “Exponent 4,” and “Power of 4”?

They mean the same thing. The number times itself 4 times (number x number x number x number).
