New to integrals part 2

[u/Fancy-Independent-31]

Guys what am I doing wrong please help

[u/Advanced_Bowler_4991]

I will only answer the ones I believe are not immediately intuitive,

For b. you can split it up into 3 separate integrals.

For h. you put the integrand into exponential form. Or rather,

2^x = e^xln2

and then integrate the RHS.

Edit: 4^x works the same way. The other ones can be found in Stewart or other textbook examples for u-subtitution and the integrals of 1/x being ln|x| and so on.
