10,000 X 100
= ______________
0000001 X .001
= ______________
10,000 X .001
= ______________
23,000 X 500
= ______________
6,200 X .02.X 2,000
= ______________
Solution:
To MULTIPLY two or more numbers using powers of 10, ADD the EXPONENTS
(power) and retain the base 10.
Thus:
10,000 X 100 = 1 X 104+2 = 106
.0000061 X .001 = 1 X 10-7+(-3) = 10-10
10,000 X .001 = 1 X 104+(-3) = 101
23,000 X 500 = 2.3 X 104 X 5 X 102 = 11.5 X 104+2 = 11.5 X 104+2
= 11.5 X 106
6,200 X .02 X 2,000 = 6.2 X 103 X 2 X 10-2 X 2 X 103
= 24.8 X 103+(-2)+3 = 24.8 X 104
