^{st}term which has to be between 1 and 10. But according to the rule, in the first term number should be less than 10 and greater than 1. So here we place decimal Point between 4 and 3 because there is no other place in the number where we can place the decimal. So the first term 000004.31, now we have to create second term and for that we have to count all digits before decimal point. After counting we find that there are six digits in front of decimal point (.). So the factor is negative six of power ten. At last we write both terms together with multiplication sign (*) in between,

4.31 * 10

^{-6}

So this is the scientific notation form of decimal number 000004.31. Now let’s take another example of decimal number which we have to convert in scientific notation form.

If the number is .00000006517, first we create 1

^{st}term of scientific notation form where we place a decimal point where number should not be less than 1 or greater than 10. So here we place the decimal in between 6 and 5.

00000006.517,

After that we create 2

^{nd}term which is

10

^{-8},

At last we write both terms together in multiplication,

6.517 * 10

^{-8}.
