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.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
