Solve for x:
(x+y)^40 = 0
Taking 40^th roots gives 0 times the 40^th roots of unity:
x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0 or x+y = 0
