Name: _____________________ Date: ________________ Mini-Lesson 6a Properties of Exponents MULTIPLICATION PROPERTY OF EXPONENTS Let m, n be rational numbers. To multiply powers of the same base, keep the base & add the exponents: EXAMPLES: a) (x 2 )(x 4 )= x 2+4 = x 6 b) (-3x 5 )(4x 2 )= (-3)( 4)x 5+2 = -12x 7 a m a n = a m+n c) (-2a 5 )(8b 3 )(3a 2 b) = (-2)(8)(3)a 5+2 b 3+1 =-48a 7 b 4 DIVISION PROPERTY OF EXPONENTS Let m, n be rational numbers. To divide powers of the same base, keep the base & subtract the exponents. m a mn a n where a 0 a EXAMPLES: a) 3 15 5 x 5 2 3 3 3 159 6 27 b) x x 2 9 3 x c) 15t 2 3t 6 15 t 3 t 6 2 5t 62 5t 4 7 2 d) 4a 2a 5 2a e) x 9 cannot be simplified as the bases x and y are different 5 y ZERO EXPONENT a 0 = 1 if a 0 EXAMPLES: 3 0 X a) 16 0 = 1 b) 1, X 0 c) (4x) 0 = 1, x 0 d) 4x 0 = 4(1)=4, x 0 e) 5(x+3) 0 = 5(1) = 5, x -3 Scottsdale Community College Page 241 Intermediate Algebra
