Question

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

Answer 1

93 X 10^9

or 93 times 10^9

Answer 2

Scientific notation has one digit before a decimal place, with the rest after, so this would mean the answer is of the form:
\[9.3 \times 10^x\]
Where x is the number of places the decimal point has been moved over.
