Given:
On average, the moon is 384,400 kilometers from the Earth.
Determine the distance 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. The given number has a total of 2 zeros and 3 non zero, therefore the magnitude or the degree of the scientific notation is 5. The non-zero number excluding the last digit will be written in decimal point.
= 3.844 x 10^5
Final answer:
= 3.844 x 10^5
