Scientific Notation

If the exponent is not negative, then a number written in scientific notation is greater than or equal to 1.

2,200,000 can be expressed as: 2.2e6 or 2.2 x 10^6

It is 3.018*10^-9 in scientific notation

1.38 x 10^5 is equal to 138,000.

It is: 1.18*10^-1 in scientific notation

It is 3*10^8

2.90 × 101

1.69 x 10^4

2.69 × 108

4.03 times 10 to the power of 8 = 403,000,000

1 000 000 in scientific notation or standard form is 1.0 x 106

It is: 2.0*109

It can be written as 9^2.

7.84 × 103

11*10^4

6.157 x 10-1

It has 14 zeroes. 100,000,000,000,000. This is 100 trillion.

Scientific notation is a way to represent very large or very small numbers.

Developments in science allow us to investigate the universe as well as the microcosm: both these involve very large and/or small numbers. Furthermore, outside of scientific there are numbers such as population counts, the value of international trade, the US budget deficit, China's currency surplus whose use is considerably simplified by using scientific notation.
