Which expression represents the largest number?
A. 40.1 x 10–6
B. 4.1 x 10–7
C. 0.411 x 10–7
D. 0.04001 x 10–5
I think it is B..?

A
clear to see if you make all numbers 10^6
Hmm. Not sure whether your exponents are positive or negative. Use ^ to indicate exponent. Not sure whether you used  instead, or just forgot the ^. If positive exponents, then convert all to 10^6 and the answer is (B).
