Solution

8- 10 :  writing a number in scientific notation is fairly simple: (first digit of the number) followed by (the decimal point) and then (all the rest of the digits of the number), times (10 to an appropriate power)

8 . 0.0005241

= 5241 x 10^(-7)

9. 6.9

6.9 x 10^0

10. 568,400

5.68 x 10^5

11. 2.3824 x 10^5 = 238240

12. 9.684 x 10^-1

= 0.9684

13. 4.62 x 10^-7

0.000000462

14. ( 3.6 x 10^6)/ (1.2 x 10^5)

= 3.6/1.2 x 10^6 -5

= 3 x 10

= 30
