We dont need to do 16-20 since we already did them. As for number 25, in your calculator go to f4, go to define, and type in f(x)=x^3. Then, for "function ff" type in f(x)*f(x), this gives you x^6. For function "f*f" this means f(f(x)) so type that in and that will give you x^9.
If you want to think about this by hand f(x)*f(x) =x^3*x^3=x^6. f(f(x))=f(x^3)=(x^3)^3=x^9.
