Finding the fourth root of a number is the opposite of multiplying a number by itself 4 times. In other words, it's the opposite of using an exponent of 4. Let's look at it mathematically.
x4 = 256
To find the fourth root of 256, we need to figure out what x is in this equation. What number can we raise to the power of 4 to equal 256? Let's think about it. . . If I plug in 2, I will get the following:
24 = 2 x 2 x 2 x 2 = 16
Thus, obviously 2 is not the fourth root of 256. Let's jump up to the number 4.
44 = 4 x 4 x 4 x 4 = 256
4 multiplied by itself 4 times give us the number we are looking for, 256! Thus, the fourth root of 256 is equal to 4
