    Integral
In summary, the conversation is about two integration problems, one involving (1+2t^8)^20 * t^7 dt and the other involving dx/(x*ln(X^5)). The person is seeking help and the conversation suggests trying u-substitution for the first problem and simplifying ln(x^5) for the second problem. However, there is a potential issue with the second problem as x cannot equal 1 or 0.

Homework Statement


I have two problems that I am stuck on, any help would be appreciated
1. the Integral of (1+2t^8)^20 * t^7 dt
2. the Integral from 0 to 1 of dx/(x*ln(X^5))



Homework Equations





The Attempt at a Solution


for 1. I know that to something like this with a lower power you should multiply it out and then use the power rule, but am I stuck multiplying out 1+2t^8 twenty times?
for 2. Calculator gave me various errors. I suspect that the answer is zero, but I'm not sure.

Thanks to anyone who decides to post

For number 1, have you tried u-substitution? Whenever you have an integral that you can't immediately figure out how to integrate, you should always try u-substitution.

For part 2, you can simplify ln(x^5) into 5lnx. Can you find the indefinite integral from here?

for question 2,
You've got a problem with this question which u will find out once u find the indefinite integral. x can't equal to either 1 or 0.
