Can someone help me solve these problems. It would be best if work was shown.
1)The equation is (5.2k-3), start k at 1, and goes infinitely. Find the partial sum S9.
2) Use the binomial theorem to expand and simplify (3a-2b^-1)^5
Please fully expand and simplify the answer. I'm having a hard time simplifying.
