    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,

    stephen

    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
