It's important to include the units when stating the speed of light, as it's not just a number but a measurement.

Here's a breakdown of the meaning:

* 3.00: This is the numerical value of the speed.

* 10^8: This is scientific notation for 100,000,000 (one hundred million).

* meters per second (m/s): This indicates the units of measurement, meaning the light travels 300 million meters in one second.
