In scientific notation, the value of the speed of light in a vacuum
 will be written as 2.995 * 10^8. When this value is represented in the form of
 a * 10^b, then, a = 2.995 and b = 8.
The value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. In this case, the scientific notation will be written as 3 *10^8.
