Question

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

Answer 1

You start with \(93,000,000 \times 1\). You then shift decimals..
\(\Rightarrow 93 \times 1,000,000\)
\(\Rightarrow 9.3 \times 10,000,000\)
\(\Rightarrow 9.3 \times 10^{7} \)
