You can put this solution on YOUR website!
sqrt 3 (-1/64)
the 3 is in the arm of the sqrt symbol and the fraction is - 1 over 64 inside of the sqrt.
:
this the cube root of -1/64, which I will write as:
3sqrt%28%28-1%29%2F64%29
:
We know the cube root of -1 is -1,(-1*-1*-1=-1)
The cube root of 64 is 4: (4*4*4=64)
therefore
3sqrt%28%28-1%29%2F64%29 = -1%2F4
