Question

Differentiate the function.
g(u) = sqrt(2)u+sqrt(7u)

g'(u)=?

Answer 1

Can somebody get me started maybe with the first two steps and then from there Ill try finishing it and then come back on and post the answer I get.

Answer 2

when a is a constant, g'(au) = a g'

You know that if
y=2x, y'=2(1)
y=3x^7, y' = 3(7x^6)
The constant is just a multiplier, and carries through.

So, what you have is

g = √2 u + √7√u
