A number written in scientific notation usually expresses a very large or very small number. It writes the value of that number as a product of 10 to some power. Let's look at some examples.
Scientific Notation
Standard Notation
5 * 10^(10)
5 0 000 000 000
5 * 10^5
5 00 000
5 * 10^1
5 0
5 * 10^0
5
5 * 10^(- 1)
0.5
5 * 10^(- 5)
0.00005
5 * 10^(- 10)
0.0000000005
To change from scientific notation to standard form, move the decimal of the given number according to the exponent of 10.
3.85* 10^(- 8)
In this case, the exponent is negative8. Therefore, we should move the decimal eight places to the left.
The standard form of 3.85* 10^(- 8) is 0.0000000385.
Scientific Notation:& 3.85* 10^(- 8)
Standard Form:& 0.0000000385
