    Hey just a simple question thats been driving me insane all night.

    could anyone please help and solve this for me:

    (64 5/12)2

    so thats (62 to the power of 5 over 12) to the power of 2

    Could anyone please kindly solve this?


    Question : do you put everything in the bracket to the power or 2? or just 5?

    thanks in advance,

    find the 12th root of 64 then put that to the power of 5 then square your answer

    When you put a power to the power of something, you just multiply the powers. So it's 5/12 x 2 = 5/6. So it's 64^(5/6) now.

    (64^(5/12))^2
    64^(10/12)
    64^(5/))
    Now get 6th root of 64.....which is 2
    2^5=
    32
