Question

If f(x) = [a - x^n]^1/n then find f(f(x)) ?​

Answer 1

Hey MaTE!!!

$f(x) = {(a - {x}^{n} )}^{ \frac{1}{n} } \\ \\ f(f(x)) = {{(a - ({(a - {x}^{n} )}^{ \frac{1}{n} } ) \: ^{n} )}}^{ \frac{1}{n} } \\ \\ = > ({ a - (a - {x}^{n} )})^{ \frac{1}{n} }$

This must be your answer.

Hope it helps
