Example 1:
(6 x 106) (2x 103) (2x 103)
_________________________ =
______4 x 10 4 Calculate the coefficient:6 x 2 x 2
___4
Find the base/exponent term:
106) (103) (103)
___________________
____ 10 4
= 6 x 10 8
Example 2:
(4 x 106) (2x 103)
__________________ =
(8 x 10 -4 )(2x 103) Calculate the coefficient:4 x 2
8 x 2
Find the base/exponent term:
106) (103)
____________
(10 -4) (103)
= 0.5x 1010 = 5 x 10 9Now Try these:
