Given the measurement:
0.0018 centimeters
Change to scientific notation.
Solution:
In order to change the value of the decimal to scientific notation, simply count the number of zeros and non zeros excluding the final digit for whole numbers. For decimals, we only include the first non-zero number. The given number has a total of 2 zeros and 1 non zero, therefore the magnitude or the degree of the scientific notation is -3. The non-zero number excluding the first digit will be written in decimal point.
= 0.0018
= 1.8 x 10^-3
Final answer:
= 1.8 x 10^-3
