64 negative cubed divided by 4 to the negative fifth.

the answer is 1/256.

Everytim I do this problem i keep getting 256. Can anyone help me?? PLEASE :)

  • MATH - ,

    (64^-3)
    --------
    4^-5

    is the same as

    4^5
    -----
    64^3
    but 64 = 8*8 = 4*4*4 = 4^3
    so we really have
    4^5
    ----
    (4^3)^3
    which is
    4^5
    ------
    4^9
    which is
    1/4^4
    wich is
    1/16^2
    which is
    1/256 yes, they won
