Scientific Notation

5.4 * 10-6

5 x 108

It is: 2.005*10^-4

It is: 2.18*10^4

3.8 x 10^-2

500

5*100

5*10^2

1.89 x 10^1

It is: 2.9*10^0

7.9 x 10^6

0.065 in scientific notation is 6.5 x 10^-2.

1,000 in Scientific Notation = 1 x 103

By changing the measurement units to a nanogram you would not require scientific notation.

1 nanogram = 1*10-9 gram or 1*10-12 kilogram

0.0005 = 5*10-4

1.02*108

1.02 x 10^5

It is 3.278*10^2 in scientific notation

Writing large or very small numbers in scientific notation helps prevent simple mistakes.

For example, in physics or chemistry, the number of basic particles in one mole of a substance is Avogadro's number, which is 602214129000000000000000 or 6.02214129*1023 in scientific notation. In the expanded form it would be quite easy to miscount the number of zeros.

13.7 billion in scientific notation is 1.37 x 1010 in the short scale, such as used in the US, and 1.37 x 1013 in the long scale, such as used in the UK.

2 x 10^-5

2.998 × 108 written in regular notation is 299,800,000

9.41 * 10-1

Its 1.5 times 10 to the negative 3 power

5.467x104
