Evaluate the Integral

Question

1. integral of (x^9+7x^6-1)/x^8 dx

2. integral of x^(1/3)*(42-x)^2 dx

3. integral of 9x+5/7x^3 dx

Answer 1

1. break it into three integrals
INT (x dx)+int(7x^-2 dx) - int x^-8dx
2.multipy it out break it into three inegrals, and use the power rule.
3. two integrals, power rule.
