LESSON 4-7 EXPONENTS & MULTIPLYING

When we multiply terms with exponents  ADD exponents of like variables

EXPONENTS & MULTIPLYING 7² 7³ = (7 7) (7 7 7) = same as… 7² 7³ = 7² ⁺ ³ = 7⁵7⁵

EXPONENTS & MULTIPLYING Simplify each expression 3 3³ = = 3 ⁴ a ⁵ a b² = = a ⁶b²

EXPONENTS & MULTIPLYING Simplify each expression -2x² 3x ⁵ = = -6x ⁷ -5c² -3c ⁷ = = 15c ⁹

EXPONENTS & MULTIPLYING Simplify each expression **When ( ) have exponent on outside… (3²)³ = = 3 ⁶ (2a ⁶ )² = = 2²a ²

PRACTICE Simplify each expression… a) m ⁵ m ⁷ b) x² x³ y y ⁵ c) 4x² 3x ⁶ d) (2³)² e) (m ⁵ )²
