Good topic, examining the use of logarithm. . . This problem is actually to calculate the order of magnitude of m/n.

Therefore, m/n = x * 10 y (0

Next, it is natural to think (lg 3 equals suggestion) that both sides take the logarithm with 10 as the base.

The left can be calculated as 93.28, while the right = LG X+Y (0

Therefore, LG x = 0.28 and y = 93.

The answer can only be D.
