When you are multiplying something such as (3x^5y^4)(2x^2y)...do you add or subtract the exponent thingies?? AHHHHHHHHHHHH.

Answer 1

You add exponents when multiplying, and subract the exponents that are in the denominator (or in a divisor).

For the two terms that you wrote, the product would be 6 x^7 y^5

Answer 2

Ohmigosh...thank you sooo much! Your my hero!
