Scientific Notation

4.0 × 103

It would be 3x10 to the 6th power.

1 times 106.

1X10^1 Scientific notation isn't really necessary for number between .00001 and 10000. It's for numbers that are intensely small or incredibly large. For those, it's quicker to write the number than to do the scientific notation.

Rene Descartes in 1637. Archimedes created a similar system.

Archimedes. his exponential counting system created to help him calculate the amount of sand needed to fill the universe [in the Sand Reckoner]

In scientific notation all numbers are written in the form: a*10b where

a is a decimal number such that 1 ≤ a < 10

and b is an integer.

1,840,000 in Scientific Notation = 1.84 x 106

74,171.7 = 7.41717 x 10^4

1,383,200 = 1.3832 x 10^6

In scientific notation, the coefficient part should be at least 1 and less than 10. To get 3350 to fit this standard while also having it multiplied by 10 to a power, you visualize moving the decimal to the left until these conditions are met.

Moved left one time:

335.0 * 10^1 doesn't work, as the coefficient part, 335.0, isn't between 1 and 10.

Moved left two times:

33.50 * 10^2 also doesn't work, and for the same reason.

Moved left three times:

3.350 * 10^3 does work, as 3.350 is at least equal to 1 and is less than 10.

Moved left four times:

0.3350 * 10^4 doesn't work, as the coefficient is too small. Moving the decimal anymore won't change this.

The answer, therefore, is 3.350 * 10^3

-0.009 = -9.0 × 10-3

7.3*10^-3

3.9*10-6

0.000015 = 1.5 x 10-5

9,460,528,400,000 = 9.4605284 × 1012

6.36 x 107

1.48, in scientific notation is 1.48 but, if you really need to show that you have written it in scientific notation, you could write it as 1.48*100

It is 8.3*10^-6

9.1256 x 10^4

It is: 1.3*10^10

7.6*10-6

No, 32.8 x 10 is incorrect. In order for it to be scientific notation, the decimal needs to go to the left one more place. It would be 3.28 X 102.

It is: 6.05*109

Scientific Notation will be used at some point especially if you are a scientist, or doctor. It is used to compute very large or very small numbers.
