Question

F(x): sq root of x ,g(x) : cube root of x, then find value: f(f(x)+g(x)) ans 1.0

Answer 1

Answer:

F( F(x) + G(X) ) = √ ( √x + ∛x )    

Step-by-step explanation:

Since we given with to two functions of x , F(x) and G(x) where

F(x) = √x

G(x) = ∛x

And we have to find the F( F(x) + G(X) )

By substituting the F(x) + G(X) instead of x in first function and then substituting the values of F(x) and G(x) we get

F( F(x) + G(X) ) = √( F(x) + G(X) )

                       = √ ( √x + ∛x )               ∵ F(x) = √x and G(x) = ∛x

Thus we get

F( F(x) + G(X) ) = √ ( √x + ∛x )
