A certain insect is approximately 4 x 10-^2 inches long. A second insect is about 1.3 x 10-^1 inches long. What is the total length of the two insects in inches? Use sciencetific notation to express your answer to 1 decimal place

Answer 1

To find the total length of the two insects, we add their lengths together.

4 x 10^-2 inches + 1.3 x 10^-1 inches = (0.4 + 1.3) x 10^-1 inches

Simplifying the decimal part, we get:

(1.7) x 10^-1 inches

So the total length of the two insects is approximately 1.7 x 10^-1 inches.
