Question 551267: HI
I am trying to prepare myself for math classes, and I came over this exercise which I do not know how to solve. The chapter is about simplifying algebraic expressions, and I do understand the basics, but not when the questions are a bit more complicated .
I am suppose to simplify this:
(-5z)(2z^2)
thank you in advance

You can put this solution on YOUR website!
(-5z)(2z^2)
---------
-5*2 = -10
--
z%2Az%5E2+=+z%5E3 Add exponents when you multiply
= -10z%5E3
