Tim is reading a book. on monday he reads 3 pages. on each day after that, he reads 3 times the number of pages that he read on the previous day. how many pages does he read on thursday?

Tuesday equals 9. Wednesday equals 27. Thursday equals 81.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
