Question

obtain the first derivatives of the following functions:
i) y=3e^2x+5
ii)y=7ln(2x+5)
iii)y=(10x+5/x)^2

Answer 1

You'll have to be more clear on the first one.

y=3e^2x+5
\(y = 3e^{2x+5}\)
\(y = 3e^{2x}+5\)
\(y = 3e^{2}(x+5)\)

Looks like you have some Chain Rule in your future. Let's see your efforts.
