Scientific Notation

4.238 x 10^5

Franco of Cologne

The number of digits in the coefficient should be exactly the same as the number of significant figures.

In scientific notation it is 1.57821*10^5 and so it is 10 to the power of 5

It is 6.86*10^5 in scientific notation

It is: 2.33*106

0.00325 = 3.25 x 10-3

4.567*103

6.8 * 10 to the -12

1.86 x 105
It is: 1.86*10^5

Scientific notation is used to show numbers raised to powers of ten. Pluto is a planet. Therefore, Pluto cannot be put into scientific notation because there are no numbers in Pluto to put to a power of ten...

in adding scientific notations you have to make their exponents the same then add the numbers. after you add coppy th x 10 and its exponent

ex.

1.25 x 10e10 + 7.5 x 10e9

=1.25 x 10e10 + 0.75 x10e10(you can see that the decimal point is move to the left so that its exponent will be equal)

=2.0 x 10e10(final ans.)

5.67 x 10^-3

0.0023 in Scientific Notation = 2.3 x 10-3

It is: 1.26*10^-3

2.793 x 10 to the power 9

4.9603 x 10^4

It is: 5.6*10^-7

It is: 3.8*10^-4

8.6 x 10^5

It is 1.54*10^4 in scientific notation

8.005X10-3

Less digits are needed for very large numbers or for very small numbers as in the following examples:-

1,000,000,000,000,000 = 1.0*1015 in scientific notation

0.000000001 = 1.0*10-9 in scientific notation

It is 13^3.
