1. 3 Integral questions

Hello,
My homework is due very soon and Ive been attempting the problems but to be completly honest I have not put in the time and dont understand the basics. I cant afford to miss a homework and would greatly appreciate some help. Please understand that I will not just take your answers and never look at the problem again. I am looking to learn from your help. Thanks in advance.

4. Thank you very much, every bit helps!

5. I'm rushing through these and am doing things while i'm doing it, so wait until i recheck them for errors before you copy them down. or better yet, you can check

6. I just checked the 2nd one it and didnt work out.

7. try the last one by yourself, if you get it wrong, i'll post the solution.

Hint: you have to do it by substituion. use u=x^5 + 1

8. sounds good, Ill post my work here. Give me a couple mins.

there's nothing wrong with the second one, i checked myself. if you differentiate 5ln(ln(4x)) you get back 5/xln(4x). try it

10. I get this far...then im stuck

u=x^5+1
Thus,
u'=5x^4

then
int 1/u^2 du

then what

The answer above is NOT correct.

then you integrate that

remember, 1/u^2 = u^-2, use the power rule

you must be really tired huh?

13. I had a 3.4 I swear

what are you inputting the answer into?

i assure you, that answer is not wrong. i've checked it myself, as well as checked it using maple AND The Integrator

there is no way its wrong

15. I am entering this as my answer for the second one 5ln(ln(4x))

and it is telling me the answer is incorrect
