The first trick is to know that adding something 1,000,000 times is the same as 1,000,000 times that number.
So, you're really asked to do 1000000 x 3.5x10^-8.
Well, 1000000 = 10^6, so we can rewrite that as:
10^6 x 3.5x10^-8
And that equals 3.5 x 10^-2.
Written in stanrd notation, that'd be 0.035.
Answer: C
