Best ResponseYou've already chosen the best response.1sorry  i didn't write it corruptly (x^(1/3)^ 3 = x^(1/3 * 3) = x^1 = x or in other words you have the cube root of and you cube it  that gives you x so if you cube both sides of the equations you get the value of x e g (x^(1/3)^ 3 =( 1/3)^3 so x =  1/3^3 = 1/27 thats one of the roots

Best ResponseYou've already chosen the best response.1note x^(1/3) is same as cube root x

Best ResponseYou've already chosen the best response.1so to find other root you do same thing with x^1/3 = 4

Best ResponseYou've already chosen the best response.0Thank you again. But do you divide x^1/3=4? Like 4/1=4.

Best ResponseYou've already chosen the best response.1just cube both sides of th equation as we did to the first one (x^(1/3)^3 = x 4^3 = 4*4*4 = 64 x = 64

Best ResponseYou've already chosen the best response.1i suggest you review the laws of indices x^a + x^b = x^(a+b) x^a / x^b = x^(ab) (x^a)^b = x^(a*b) = x^ ab
