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.
The square root of 82 cannot be reduced as a surd.

9 and 10.
Negative fourth root of a number= 1/the fourth root of the number. Fourth root of 625= 5 (5*5*5*5) 1/5
The square root is 6, so the fourth root is the square root of 6, or about 2.45. ■
