How to find fourth root of 82?

Answer 1

You can do this on any scientific calculator (raise 82 to the power (1/4)). To do it without such a function, for instance, with pencil and paper, is a lot of work; one method is as follows:

4th. root means you want a number that, when raised to the fourth power, gives 82. Therefore, you can try different numbers, raising them to the 4th. power, until you get close enough.

If you have a calculator that only does square roots, you can also take the square root of 82, and then take the square root of the result.
