One uranium atom has a diameter of 3.5×10−8 centimeters. What is the sum of 1,000,000 uranium atoms’ diameters, in centimeters, written in standard notation?

A.) 3.5
B.) 0.35
C.) 0.035
D.) 0.0035

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.

C

the answer is true.
