Best ResponseYou've already chosen the best response.0or Take your calculator. Everywhere you see and x, replace it with (3) 3 in brackets. Same for y and z. and also By hand. Work out x^2, y^3. and replace them in the equation with your result (in brackets). Remember that 27  (8) will change to 27 + 8 etc.
