Given the number:

0.000398

Change to scientific notation.

Solution:

In order to change a number in standard form to scientific notation, simply count the number of zeros and non zeros excluding the final digit, hence for decimals, we count the first non-zero number only. The given number has a total of 43zeros and 1 non zero, therefore the magnitude or the degree of the scientific notation is -4, negative since we have a decimal. The remaining non-zero numbers will be written as decimal.

3.98 x 10 ^ -4

Final answer:

= 3.98 x 10 ^ -4
