Question

(6.91x10^-2)+(2.4x10^-3)

Answer 1

Answer: 0.06934

Step-by-step explanation:

To add the numbers (6.91x10^-2) and (2.4x10^-3), we need to ensure that they have the same exponent.

1. Rewrite the numbers in scientific notation with the same exponent. In this case, we can rewrite (6.91x10^-2) as (6.91x10^-2) and (2.4x10^-3) as (0.024x10^-2).

2. Now, we can add the numbers: (6.91x10^-2) + (0.024x10^-2).

3. When adding numbers in scientific notation, we only add the coefficients and keep the same exponent. In this case, add 6.91 and 0.024 to get 6.934.

4. The final answer in scientific notation is 6.934x10^-2.

Therefore, (6.91x10^-2) + (2.4x10^-3) is equal to 6.934x10^-2.

I hope this helps :)
