Best ResponseYou've already chosen the best response.0No 3x3x3x3 =81 I just factored the number so you can se tha it's formed by 3x3x3x3 Now the cube root will eliminate 3 of these 3 of the the root, So you get 3cbrt(3)

Best ResponseYou've already chosen the best response.0Now, the width A number raised to a fraction can be transformed into a root like this A^b/c Croot(a^b) So 2 to the2/3 Will be cube root of 2^2 How much is Cube root of 2^2?
