P.2 Exponents and Radicals Properties of Exponents a m a n = a m+n a 0 = 1 (ab) m = a m b m (a m ) n = a mn

Ex. 1a.(-3ab 4 )(4ab -3 ) b.(2xy 2 ) 3 c.3a(-4a 2 ) 0 = -12a 2 b = 8x 3 y 6 = 3a Ex. 2

Scientific Notation Ex. 3 Write each number in scientific notation. a.0.0000782 b.836,100,000 = 7.82 x 10 -5 = 8.361 x 10 8 Ex. 4 Write each number in decimal notation. a.9.36 x 10 -6 b.1.345 x 10 2 = 0.00000936 = 134.5
