The problem is: 5x10^n=0.005 then n=? A. -5 B. -3 C. -2 D. 2 E. 3 Answer by stanbon(57967)   (Show Source): You can put this solution on YOUR website!5x10^n=0.005 then n=? A. -5 B. -3 C. -2 D. 2 E. 3 ----------------- If you start with 5.0 and end up with 0.005 you must have moved the decimal point 3 spaces to the left. Multiplying by 10^-3 will do this. So the answer is "B" or -3 Cheers, Stan H.
