Assignment: Multiply and divide monomials
Anna71 [15]

Answer:

10<em>m</em>

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.

10<em>m</em>^3/(10<em>m</em>)(<em>m</em>)

First, in the denominator, since that <em>m</em> are being multiplied and they are the same <em>terms, </em>their exponents add:

10<em>m</em> * <em>m</em>

10<em>m</em>^1 * <em>m</em>^1

1 + 1 = 2

10<em>m</em>^2

Then, since that <em>m </em>are now being divided, their exponents subtract:

10<em>m</em>^3 / 10<em>m</em>^2

3 - 2 = 1

10<em>m</em>^1

10<em>m</em>
