I have solved the following and I am writing just their answers with it, please let me know if these are correct. thanks 1. Simplify, and write in the base of 3: (9^x . 3^4x)^2 answer: 3^12x 2. Differentiate and simplify y= (e^x - 1) / x^2 answer: (xe^x - 2e^x +2) / x^3

just copy and paste your question into google and the exact same question pops up on the first link. the post you posted before is the 3rd link down.
