The document discusses the rules for dividing monomials by monomials: - Like bases are kept the same, and the exponent of the resulting monomial is found by subtracting the smaller exponent from the larger exponent. - If the larger exponent is in the numerator, the result goes in the numerator. If the larger exponent is in the denominator, the result goes in the denominator. - Examples are provided to demonstrate applying these rules to simplify expressions involving dividing monomials.

5. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents:
Like bases, subtract smaller from
the larger exponent to get the
new exponent and keep the same

If the larger exponent is in the
numerator, the result goes in the
numerator.

6. Dividing a Monomial by a Monomial
Apply the rules for dividing
exponents: x5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base.
If the larger exponent is in the
numerator, the result goes in the
numerator.

Apply the rules for dividing
exponents: x 5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the
numerator.

new exponent and keep the same
base. =x 5− 3
If the larger exponent is in the
numerator, the result goes in the 2
numerator. =x

9. Dividing a Monomial by a Monomial

exponents: x 5
Like bases, subtract smaller from 3
the larger exponent to get the
x
new exponent and keep the same
base. =x 5− 3

numerator, the result goes in the 2
numerator. =x
If the larger exponent is in the
denominator, the result goes in
the denominator.

29. Still a little confused?
Here’s another tiny lesson dividing a
polynomial by a monomial.
Only view the “Steps for Dividing a
Polynomial by a Monomial.”

30. It’s Practice time...
Go to the Regents Prep website to
practice dividing a polynomial by a
monomial. Only practice questions 1
through 7!
Message or Pronto me if you have
questions.

31. Shall we Play a GAME?
Check your knowledge on Dividing Polynomials by playing
Jeopardy. Ok, technically it’s called Challenge Board but
it’s the same idea! There are 4 categories: horseshoes,
handgrenades, doesn’t count, and polynomial long division.
Polynomial long division is not covered in Algebra 1 so
either stay away from this topic or challenge yourself!
You have the option to play alone or against a friend or
family member.
You could even arrange a time with a classmate to meet
on Pronto to play. Try the App Share feature to see the
same game board!

32. Congratulations!
You’ve finished the notes and practice
for Dividing a Polynomial by a Monomial.
You are now ready to proceed to the

Good luck!
