Given the number:
0.00078
Write in 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 number of zero and the first non-zero number only The given number has a total of 3 zeros and 1 non zero, therefore the magnitude or the degree of the scientific notation is -4. We equate it as a negative since we have a decimal number. The non-zero number excluding the last digit will be written in decimal point.
0.00078
= 7.8 x 10^-4
Final answer:
= 7.8 x 10^-4
