Um. i was out the day of the lesson for this assignment, and i read the book's lesson, but it doesn't explain everything. Basically, it says

so i learn that a^3 • a^2 (in this situation) is basically adding the exponents. no problem.

then it says...

ok, so you multiply parethetical exponents and outside exponents. again, nothing difficult.

then it says..

add the exponent to everything in parenthesis. again, easy.

but then you get to the problems...

um. so like, you have 3b^3, and multiply it by 1b? so it's... still 3b^3? or did i mess up somewhere?

5^3=125, so it's 125 • ...5a^8? or 5a^6? @_@

buhhh.... 4x • (x^4)^2.. 4x • x^8... 4x^8?

there's more confusing ones, but hopefully i can sort most of them out if i get these figured out...thanks
