5.3 Multiplying Monomials

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

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

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

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

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