When you're dealing with scientific notation (especially when you use an order of operations such as adding on it), it's important to know that you cannot add 10^2 to 3 (for example).
(3 x 10^5) + (5 x 10^8)
When adding exponents, you're only adding the exponents together and not changing the original number (10).
5 + 8 = 13
We now have a sum of 3x5 x10^13
Multiply 3 by 5 to get your new expression.
3 x 5 = 15
15 x 10^13 is what we're left with.
Your answer is A.)
I hope this helps!
