To find the total length of the two insects, we need to add their lengths.
The length of the first insect is 4 x 10^-2 inches.
The length of the second insect is 1.3 x 10^-1 inches.
Adding these two lengths, we get:
4 x 10^-2 + 1.3 x 10^-1
To add these numbers in scientific notation, the exponents must be the same.
We can rewrite 4 x 10^-2 as 0.04 x 10^0, and 1.3 x 10^-1 as 0.13 x 10^0.
Adding these two numbers, we get:
0.04 x 10^0 + 0.13 x 10^0 = 0.17 x 10^0
Since 0.17 x 10^0 is equal to 0.17, we can write the total length as:
0.17 inches.
