Solution to
Dividing Using Scientific Notation
Frame 5-21.
a. 6 x 10 7
Scientific notation can also be used in division.
Consider the problem: 800,000 200,000,000.
(3x2 x 10 (4+3)
b. 101 or 0.1
By using scientific notation, you can change the appearance of the
problem to 8 x 10 5 divided by 2 x 10 8.
5x2 x 10 46
10 x 102
To solve the problem, you
1 x 101 X 102
1 x 1012
(1) Divide the coefficients (numbers in front).
101
(2) Subtract the exponents. The difference will be your
new power of 10.
(3) Rewrite the answer so it is in scientific notation format,
if needed.
8 x 10 5 2 x 10
8
= 8 2 x 10 58 = 4 x 10 3 (or 0.004)
Solve this problem:
5 x 10 7 4 x 10 5
