The speed of light in a vacuum is 299,792,458 meters per second. which number written in scientific notation is the best approximation of the speed of light

The scientific notation can be defined as the way of expressing a larger numerical value into a very small number. This is done by using a single decimal form of the number along with the remaining numbers raised to the power of ten.

The number suiting the best approximation for the speed of light is:

The determination of the base and power are as follows:

Given :

The speed of light in a vacuum is 299,792,458 meters per second.

The total number of digits is 9

As per the rules, the power to 10 is always a total number of digits less than 1.

So the power to 10 will be:

The speed of the vacuum will be 2.99792458, which is equivalent to 3.0

The best approximation of the speed of light would be meters per second.

Step-by-step explanation:

Scientific notation is a famous way to express a very large or a very small number as the product of a decimal form of number ( between 1 and 10) and powers of ten.

For example 1300000 can be written as .

Given : The speed of light in a vacuum is 299,792,458 meters per second.

Total digits = 9

Power of ten = 9-1=8

Now , the speed of light in a vacuum can be expressed as  meters per second.

Since

So , the best approximation of the speed of light would be meters per second.
