your method seems sound though you are out by a factor of 10. \(4.42(10^{-2}) \times 3.8 = 0.168\) \(2(10^{-3}) \times 841 = 1.68\) i just wonder if it's worth posting a scan of the question or a link...

so that gives \(4.43 \times 10^{-1}\) or in the form the question requires: a 4 b 4 c 3 d 1 which starts to *resemble* the answer you posted, when you posted it as "3144"
