This is pretty straightforward.......we want x on one side of the equation by itself

cubrt(x) -m = n      add m to both sides of the equation

cubrt(x) = n+m      Now cube each side

x = (n+m)^3

Solve for x:

x^(1/3) - m = n

 

Isolate terms with x to the left hand side.

Add m to both sides:

x^(1/3) = m + n

 

Eliminate the cube root on the left hand side.

Raise both sides to the power of three:

x = (m + n)^3 = m^3 + 3m^2n + 3mn^2 + n^3
