To subtract 4.66 x 10^-5 from 7.34 x 10^-7, we need to make sure the exponents are the same.
First, let's convert 4.66 x 10^-5 to scientific notation with the same exponent as 7.34 x 10^-7:
4.66 x 10^-5 = 0.0000466 x 10^-5 = 4.66 x 10^-7
Now, we can subtract the two numbers:
7.34 x 10^-7 - 4.66 x 10^-7 = (7.34 - 4.66) x 10^-7 = 2.68 x 10^-7
Therefore, the correct answer is C) 2.68 x 10^-7.

Apologies for the mistake. Let's redo the math correctly.
To subtract 4.66 x 10^-5 from 7.34 x 10^-7, we need to make sure the exponents are the same.
First, let's convert 7.34 x 10^-7 to scientific notation with the same exponent as 4.66 x 10^-5:
7.34 x 10^-7 = 0.00000734 x 10^-5 = 7.34 x 10^-9
Now, we can subtract the two numbers:
4.66 x 10^-5 - 7.34 x 10^-9 = (4.66 - 0.00000734) x 10^-5 = 4.65266 x 10^-5
Therefore, the correct answer is A) 4.65266 x 10^-5.
