1) evaluate: integral of
(3x^2 + 5x - 1 + 3/x) dx

x^3/3 + x^2/5 - x Is this correct?

2) evaluate: integral of
(5e^7x + srqtx) dx

I am not sure with this. Could you please explain. Thank you for you help!

1. what about the INT 3/x dx term?
That is 3lnx

Int 5e^7x = 5/7 e^7x

INT sqrtx= 2/3 x^3/2
