Answer:
-30m^9
Explanation:
The commutative property of multiplication tells you that you can rearrange this to ...
(-5)(6)(m^2)(m^7)
An exponent tells you how many times the base is a factor of the product. When you count up the factors of m, you find there are 2 and then 7 more, for a total of 9 factors of m. Using an exponent, those can be written as m^9.
Of course, the product of -5 and 6 is (-5)(6) = -30.
The simplified form of your product is ...
-30m^9
