Hello

I was wandering can anyone help me with rationalization of denominator in this fraction: | a/sqrt(a * sqrt(a)) |

I tried to solve this like this: I multiply both numerator and denominator with | sqrt(a * sqrt(a)) | to get | a * sqrt(a) | in the denominator. Then I multiplied both numerator and denominator with | sqrt(a) to get | a^2 | in denominator. Please tell me if this is right and if it is not, help

P.S. I have a final solution to this problem (in the book), and it is | sqrt[3](a) | but I can't get to that help please
