Question

solve the following and put in scientific notation:

1.) 6.6 x 10^-8 divided by 3.3 x 10^-4

2.) 7.4 x 10^10 divided by 3.7 x 10^3

3.) 2.5 x 10^8 divided by 7.4 x 10^2

4.) (2.67 x 10^-3) - (9.5 x 10^-4)

5.) (1.56 x 10^-7) + (2.43 x 10^-8)

6.) (2.5 x 10^-6) x (3.0 x 10^-7)

7.) (1.2 x 10^-9) x (1.2 x 10^7)

8.) (2.3 x 10^4) x (2.0 x 10^-3)

give the correct number of sig figs:

9.) 2.9910 m

10.) 5600 km

11.) 0.00670 kg

12.) 809 g

solve the problems with the correct number of sig figs

13.) 2.674m divided by 2.0 m

14.) 5.25L x 1.3L

15.) 9.0cm + 7.66cm + 5.44cm

16.) 10.07 g - 3.1g

solve for x:

17.) 3x divided by y = 6g divided by b

18.) d = t divided by x

19.) 2x^2 divided by 3 = dg

20.) 2 times the square root of x divided by c =y
