How many times larger is 9×10−8 than 3×10−12?
A. 6×10^−3
B. 3×10^4
C. 3×10^3
D. 6×10^−4
To find out how many times larger 9×10^-8 is than 3×10^-12, we need to divide 9×10^-8 by 3×10^-12.
(9×10^-8) / (3×10^-12) = (9/3) × 10^(-8-(-12)) = 3 × 10^4
So, 9×10^-8 is 3×10^4 times larger than 3×10^-12.
Therefore, the answer is B. 3×10^4.
