To find the total length of the two insects in inches, we need to add their lengths.
The length of the first insect is 4×10^(-2) inches.
The length of the second insect is 1.3×10^(-1) inches.
Adding these lengths, we get:
4×10^(-2) + 1.3×10^(-1) = 0.004 + 0.13 = 0.134
So the total length of the two insects is 0.134 inches.

Apologies for the mistake. Let's recalculate.

The length of the first insect is 4×10^(-2) inches.
The length of the second insect is 1.3×10^(-1) inches.

Adding the lengths, we get:
(4×10^(-2)) + (1.3×10^(-1)) = 0.04 + 0.13 = 0.17

So the total length of the two insects is 0.17 inches, expressed in scientific notation as 1.7×10^(-1) inches.
