5-47.

The average distance from the earth to the moon is 3.844 × 108 meters. If the length of the average pencil is 1.8 × 10−1 meters, approximately how many pencils would need to be connected together to reach the moon? Use appropriate precision in your answer. Homework Help ✎

This would require dividing these two numbers in scientific notation.
Review the Math Notes box in Lessons 1.3.1 and 1.3.2.

$\frac{3.844 \times 10^{8}}{1.8 \times 10^{-1}}$
