d. 0.000 000 0217 g _______________________________________________
e. 750 in. _______________________________________________________
f. 0.5003 s ______________________________________________________
6. Without calculating the result, find the number of significant figures in the
following products and quotients.
a. 0.00532  4.0009 ______________________________________________
b. 0.0080750  10.037 ____________________________________________
c. (3.52 &times; 1011)  (7.823 &times; 1011)_____________________________________
7. Calculate a + b, a  b, a  b, and a  b with the correct number of significant
figures using the following numbers.
a. a = 0.005 078; b = 1.0003
a + b = ______________________
a  b = ______________________
a  b = ______________________
a  b = ______________________
b. a = 4.231 19  107; b = 3.654  106
a + b = ______________________
a  b = ______________________
a  b = ______________________
a  b = ______________________
