Question

Compare 7 x 103 and 5 x 102. A) 7 x 103 is 14 times larger than 5 x 102. B) 7 x 103 is 4 times larger than 5 x 102. C) 7 x 103 is twice as large as 5 x 102. D) 7 x 103 is 5 times larger than 5 x 102.

Answer 1

7 * 10^3 = 7 * 1000 = 7000
5 * 10^2 = 5 * 100 = 500

7000/500 = 14

so 7 * 10^3 is 14 times larger then 5 * 10^2 <==
