To add the two lengths in scientific notation, we add the coefficients and keep the same exponent.
So, $(4 \times 10^{-2}) + (1.3 \times 10^{-1}) = (4 + 1.3) \times 10^{-2} = 5.3 \times 10^{-2}$.
To express our answer to 1 decimal place, we round 5.3 to the nearest tenth to get $\boxed{5.3 \times 10^{-2}}$.
A certain insect is approximately 4 × 10^-² inches long. A second insect is about 1.3 × 10^-¹ inches long. What is the total length of the two insects in inches? Use scientific notation to express your answer to 1 decimal place.

What is the sum of 6.3×10³ and 2.41×10⁴? Use scientific notation to express your answer
To add the two numbers, we add the coefficients and keep the same exponent.
So, $(6.3 \times 10^3) + (2.41 \times 10^4) = (6.3 + 2.41) \times 10^4 = 8.71 \times 10^4$.
Therefore, the sum of $6.3 \times 10^3$ and $2.41 \times 10^4$ is $\boxed{8.71 \times 10^4}$.
So, $(6.3 \times 10^3) + (2.41 \times 10^4) = (6.3 + 2.41) \times 10^4 = 8.71 \times 10^4$.
Therefore, the sum of $6.3 \times 10^3$ and $2.41 \times 10^4$ is $\boxed{8.71 \times 10^4}$.
wrong again, bot!
4 * 10^-2 + 1.3 * 10^-1
= 0.43 * 10^-1 + 1.3 * 10^-1
= 1.73 * 10^-1
4 * 10^-2 + 1.3 * 10^-1
= 0.43 * 10^-1 + 1.3 * 10^-1
= 1.73 * 10^-1
Apologies for the error in my previous response.
You are absolutely correct. The sum of $4 \times 10^{-2}$ and $1.3 \times 10^{-1}$ is indeed $1.73 \times 10^{-1}$. Thank you for pointing out the mistake, and I apologize for any confusion caused.
