Question

The distance from the Earth to the sun is 93 million miles or 93,000,000 miles. How would this number be written in scientific notation?

Answer 1

Answer: To write 93,000,000 in scientific notation, we need to move the decimal point to the left so that there is one non-zero digit to the left of the decimal point.

Counting the number of places we move the decimal point, we get:

93,000,000 = 9.3 x 10^7

Therefore, 93 million miles can be written in scientific notation as 9.3 x 10^7 miles.
