IV- Before
you start this section be sure you are familiar with: 1)
An introduction to scientific notation; Scientific
Notation problems involving multiplication and division. Example
1:
(6
x 10^{6}) (2x 10^{3}) (2x 10^{3})
^{_________________________} = ______4
x 10^{ 4} | Calculate
the coefficient: 6
x 2 x 2 ___4 |
Find the base/exponent term:
10^{6}) (10^{3}) (10^{3}) ^{___________________}
____ 10^{ 4} |
= 6 x 10^{ 8} | Example
2:
(4
x 10^{6}) (2x 10^{3}) ^{__________________}
= (8 x 10^{ -4} )(2x 10^{3})
| Calculate
the coefficient: 4
x 2 8 x 2 | Find
the base/exponent term: 10^{6}) (10^{3}) ^{____________}
(10^{ -4}) (10^{3}) |
= 0.5x 10^{10 } =
5 x 10^{ 9} | Now
Try these: (write
your answers in the form of coefficientx10^exponent) If your answer is 3.5 x 10^{
3 } you should type 3.5x10^3 in the box then click the submit
button). (write

(5
x 10^{6}) (2x 10^{3}) (3x 10^{3})
^{_________________________} = ______5
x 10^{ 4} | Now
Try these: (write
your answers in the form of coefficientx10^exponent) If your answer is 3.5 x 10^{
3 } you should type 3.5x10^3 in the box then click the submit
button). 1) What
is the ratio of Milky Way radius to our solar system radius given that, the distance
from pluto to sun is 5.9×10^{ 12 } meters and the Milky Way disk
radius is. 3.9×10^{20 }meters. Round the coefficient to the nearest
tenth. 2) The speed of light
is 3 x 10^{ 8 } meters/second. If the sun is 1.5x 10^{11} meters
from earth, how many seconds does it take light to reach the earth. Express your
answer in scientific notation |
