A monomial is a

• 1. number,
• 2. variable, or
• 3. a product of one or more numbers and
  variables.
• Examples
• 5
• y
• 3x2y3

Why are the following not monomials? x y

• addition
• division
• 2 - 3a
• subtraction

4
Multiplying Monomials

• When multiplying monomials, you ADD the
  exponents.
• 1) x2 x4
• x24
• x6
• 2) 2a2y3 3a3y4
• 6a5y7

6
Power of a Power

• When you have an exponent with an exponent, you
  multiply those exponents.
• 1) (x2)3
• x2 3
• x6

8
Power of a Product

• When you have a power outside of the parentheses,
  everything in the parentheses is raised to that
  power.
• 1) (2a)3
• 23a3
• 8a3
• 2) (3x)2
• 9x2
