1. 5.3 Multiplying Monomials

2. Monomial: X 4x3 x3 + 4 X X 2x2y -8 An expression that is either a:
(1) numeral or constant, ex : 5
(2)a variable, ex: x
(3)or a product of numerals and variables ex: 5x
(4)variables with whole number exponents. Ex: x²
If the monomial is a numeral, it is called a constant.
Excludes: “+”, “-”, and if exponent is negative or a fraction. X
4x3
x3 + 4 X X
2x2y -8

3. To Multiply Monomials:
Multiply the numbers
Add exponents of like bases

4. Multiply:
(7y)(2y2)
= 14y3

5. Multiply:
(5y-2)(3y7)
= 15y5

6. Multiply:
(-3y3)(4xy5)
= -12xy8
