Answer:
10m
Step-by-step explanation:
Your teacher probably told you the necessary fundamentals of monomials. So, I'll just teach you the things needed for this particular question.
10m^3/(10m)(m)
First, in the denominator, since that m are being multiplied and they are the same terms, their exponents add:
10m * m
10m^1 * m^1
1 + 1 = 2
10m^2
Then, since that m are now being divided, their exponents subtract:
10m^3 / 10m^2
3 - 2 = 1
10m^1
10m
