Best ResponseYou've already chosen the best response.1(2)(2)(2)= (2)^3=8 this is a cubed of 2,,, now its reversed is the cube root cube root of 8=(8)^(1/3) =2

Best ResponseYou've already chosen the best response.1algebraically,,,,if (b)^1/3=a here lets put both sides to the power of 3 [ (b)^1/3 ]^3=[a]^3 [ (b)^3/3 ]=[a]^3 [ (b)^1 ]=[a]^3
