E N D
ObjectivesThe student will be able to: 1. multiply monomials. 2. simplify expressions with monomials.
A monomial is a 1. number, 2. variable, or 3. the 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
Multiplying Monomials When multiplying monomials, you ADD the exponents. 1) x2 • x4 x2+4 x6 2) 2a2y3 • 3a3y4 6a5y7
Simplify m3(m4)(m) • m7 • m8 • m12 • m13
Power of a Power When you have an exponent with an exponent, you multiply those exponents. 1) (x2)3 x2• 3 x6 2) (y3)4 y12
Simplify (p2)4 • p2 • p4 • p8 • p16
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
Simplify (4r)3 • 12r3 • 12r4 • 64r3 • 64r4
Power of a Monomial This is a combination of all of the other rules. 1) (x3y2)4 x3• 4 y2• 4 x12 y8 2) (4x4y3)3 64x12y9
Simplify (3a2b3)4 • 12a8b12 • 81a6b7 • 81a16b81 • 81a8b12
