Example Question #22 : How To Divide Monomial Quotients

Divide the following monomial quotients:

\(\displaystyle \frac{42x^{3}y^{2}}{6xy}\)

Possible Answers:

\(\displaystyle 6xy^{2}\)

\(\displaystyle 7x^{2}y\)

\(\displaystyle 14xy\)

\(\displaystyle 7xy\)

Correct answer:

\(\displaystyle 7x^{2}y\)

Explanation:

To solve this problem, split it into two steps:

1. Divide the coefficients

\(\displaystyle \frac{42}{6}=7\)

2. Divide the variables. We also need to remember the following laws of exponents rule: When dividing variables, subtract the exponents.

\(\displaystyle \frac{x^{3}}{x} =x^{3-1}=x^{2}\)

\(\displaystyle \frac{y^{2}}{y}=y\)

Combine these to get the final answer:

\(\displaystyle 7x^{2}y\)

\(\displaystyle xyz\)

Correct answer:

\(\displaystyle x^{2}yz\)

Explanation:

To solve this problem, divide the variables. We also need to remember the following laws of exponents rule: When dividing variables, subtract the exponents.

\(\displaystyle \frac{x^{3}}{x} =x^{3-1}=x^{2}\)

\(\displaystyle \frac{y^{2}}{y}=y\)

\(\displaystyle \frac{z}{1}=z\)

Combine these to get the final answer:

\(\displaystyle x^{2}yz\)

\(\displaystyle \frac{6}{3}=2\)

2. Divide the variables. We also need to remember the following laws of exponents rule: When dividing variables, subtract the exponents.

\(\displaystyle \frac{x}{1} =x\)

\(\displaystyle \frac{y}{y}=1\)

Combine these to get the final answer:

\(\displaystyle 2x\)

Example Question #73 : Monomials

Divide the following monomial quotients:

\(\displaystyle \frac{yz^{2}}{xy^{2}}\)
