A number written in scientific notation usually expresses a very large or very small number by writing its value 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.
3.9* 10^6
In this case, the exponent is positive6, so we should move the decimal six places to the right.
Therefore, the standard form of 3.9* 10^6 is 3 900 000.
Scientific Notation:& 3.9* 10^6
Standard Form:& 3 900 000
