Question

Evaluate the integral

Answer 1

\[I=\int\limits_{1}^{4} \sqrt{x} (3+\frac{ 2 }{ x }) dx\]

Answer 2

Ok so what I would do is start by distributing the sqrt(x) to form
\[I=\int\limits_{1}^{4}3\sqrt{x}+\frac{ 2 }{ \sqrt{x} }dx\]

Answer 3

ooo so would u=sqrt x ?

Answer 4

oh wait would i even need to use u-substitution if i did it this way??

Answer 5

I dont think you need to use u-subs for this.

Answer 6

okay thanks :)

Answer 7

MIght work anyways though, but i didnt try it
