Which expression is equivalent to
(8.8 x 10^11)/(2.2 x 10^-3) ?
A. 4 x10^10
B. 4 x 10^14
C. 40 x 10^12
D. 4 x 10^8
To divide the two numbers, we can simply divide the coefficients and subtract the exponents as follows:
(8.8 x 10^11) / (2.2 x 10^-3) = (8.8/2.2) x 10^(11 - (-3)) = 4 x 10^14.
Therefore, the answer is B. 4 x 10^14.
