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....
