Question

The average distance from the earth to the sun is approximately 93,000,000 miles. Write this distance in scientific notation.

Answer 1

In scientific notation, you want to have only the front digit in front of the zero. To do this, you move the point across until you have 9.3. You would have to move the point across 7 digits. You have to multiply this by a number of tens, 7 tens. So..... 9.3 x 10^7
