Question

Someone please help me with this question

Answer 1

10x

Explanation:

By definition

`(f\codt g)(x)=f(x)\cdot g(x)`

So we just need to multiply the two functions

`(f\cdot g)(x)= f(x)\cdot g(x)\\=√(2x)\cdot √(50x)\\=√((2x)\cdot (50x))=√(100x^2)\\=10√(x^2)\\=10x \text{ since x is non negative}`
