Simplify. Answers should be in Scientific Notation. Type the coefficient in the blue box. Type the exponent in the purple box. If your answer is correct, it will turn green; if your answer is incorrect, it will turn red. (6x107) (9 107) (9 109) (3.6 109) = x 10 X * 10 (5 10-12) (8x10-12) = (7 10-4) (4.3 10-4) (7.2 105)+(5.9 105) = (6.2-108) (5.9 108) (1.6 107) + (3.4 105) X (1 106) (2.1 104) (8.6 108) + (7.3 10) (1 105) (9 10 ) (5.6 108) (7109) (2.3 10) (8.6 10') X X * 10 * 10 X 10 X 10 X x 10 x 10 * 10 x 10 X 10 X 10
