Add. Write your answer in scientific notation. (5.27 × 10^6) + (3.9 × 10^5)

To add the two numbers in scientific notation, we need to ensure they have the same exponent.

1. Rewrite (3.9 times 10^5) to have the same exponent as (5.27 times 10^6):

[

3.9 times 10^5 = 0.39 times 10^6

]

2. Now add the two numbers:

[

(5.27 times 10^6) + (0.39 times 10^6) = (5.27 + 0.39) times 10^6 = 5.66 times 10^6

]

Therefore, the final answer is:

5.66 × 10^6.
