Algebra Chapter 1: Simplifying Rules in Section C:
C. Multiplying Expressions on multiplying monomial expressions...

You have an example problem to explain multiplying polynomials:
(2rs³)(-3r³s²) = ?

Your result in the online material is:
-6(r^4)s(5^5)

I don't understand, is this a typo or error?

Shouldn't the result of your sample problem be this:
-6(r^4)(s^5)

Please let me know. Thanks.

erickmiller,
Yes, it looks like a misprint. We will check on it.

The right answer is -6(r^4)(s^5)
