Amaya designed an experiment to test how sunlight affects a plant's growth. She chose a location on her patio and set up 4 identical plants. She measured the growth of each plant daily and created a graph of her results.

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.

it's all four options.
