Best ResponseYou've already chosen the best response.1now the key to solve this is to know that anything times 0 equals 0 right? so we have 2 options... if x = 0 then; (0)(08) = 0 and if x = 8 then; (8)(88) = (8)(0) = 8 So we have to test for x = 0 and x = 8 in the original problem to see if these are good....

Best ResponseYou've already chosen the best response.1\[0=\sqrt{8*0}\] thats true \[8 = \sqrt{8*8} = \sqrt{64}\]and thats tru; so yes x = 0 or 8
