how do i evalute this problem if possible.
i will decribe it
it has an index of 3 then a squaroot sign then for the radicand (-64)
since the cube root of 64 is 4(4 times 4 times 4 = 64).. the (-) part, you just tack on, since a (-) times (+) times (-) equals a (-). so the answer will be -4.
Check: -4 time -4 = 16.
16 times -4 = -64
Hope this helps....
