4+%2B+sqrt%28x%5E3%2By%5E3%29%22=%22%22z 

Isolate the square root on the left

sqrt%28x%5E3%2By%5E3%29%22=%22%22z-4 

x%5E3%2By%5E3%22=%22%22%28z-4%29%5E2

y%5E3%22=%22%22%28z-4%29%5E2-x%5E3

y%5E3%22=%22%22%28z-4%29%28z-4%29-x%5E3

y%5E3%22%22=%22%22z%5E2-8z%2B16-x%5E3

y%22%22=%22%22root%283%2Cz%5E2-8z%2B16-x%5E3%29
