Question 664827
How can I simplify the following problem:
(-3m‸7)(-7m‸2) 
Thank you!

First you multiply the numerical coefficient which is -3 and -7. Then you multiply the variables which is m^7 and m^2. In order to multiply same variables just add the exponent, if different variables just combine them and copy  the exponents. So (-3m‸7)(-7m‸2) is equal to,   21m^9
