Hey there! these are some questions that I am having some trouble with. They are probably easy for most people, but I am aboslutely horrendous so any and all help would be excellent! Thank you!

1) (3x - 5)^4

2) (4x2y6z)^2 (-x5y7z8)^6

3) 4x^4 - 4x^3 + 3x^2 - 5x +2 (divided by) 2x-3

Thanks again!
