Question 473778
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((-1)/64)}}}
:
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((-1)/64)}}} = {{{-1/4}}}
