    The fifth root of 32 is 2.

    You can find this by factoring out one root at a time until you have 5 of the same. So we start with 32 and we factor out a 2.

    32

    2 * 16

    Then we can do the same with the 16.

    2 * 16

    2 * 2 * 8

    And continue the process until we have only 2s

    2 * 2 * 8

    2 * 2 * 2 * 4

    2 * 2 * 2 * 2 * 2

    Since there are 5 of them, it is the 5th root of 32.
