I tried to figure this out on my own I've gone through my math book and to several websites and I can't even figure out where to start....

actually if it is 3 √ ( -64 [x+1]^3 ) then it is equal to 3 [ 8 { (-x - 1 )√(-x-1)] ...-1 = (-1)^3
you note that for the square root to exist you need [ x +1 ] ≤ 0 ,
so -x-1 ≥ 0
you could write it as 24 | x + 1 | √ | x + 1 |
