rewrite the following in standard form, a) 0.02 × 10^{-8}
Answers
Answer:
NASA tells us that the distance from the Earth to the nearest star is 40,208,000,000,000 kilometers. If your eyes sink into the back of your head when you see a number like that, imagine if you had to make calculations with it. Just to multiply or divide it by the speed of light, you would need a calculator so large it wouldn't fit in your hand. Scientists handle very large numbers like this one, as well as very small numbers, by converting them to standard form, which is a decimal number followed by an exponent of 10. The decimal can be accurate to as many places as desired, but it's usually rounded to two. The value of the exponent indicates the magnitude of the number. In standard form, the distance to the nearest star is a much more manageable 4.02 X 1013 km.
