Take any two of the four numbers 2, 3, 4 and 5. Use one as the base of the logarithm and the other as the true number of the logarithm 1) How many different logarithms can be obtained? 2) how many of them are larger than 1?

LOG100 25 = (1g25) / (LG100) = (LG25) / 2 why does LOG100 25 become (LG25) / (LG100) and how does it become (LG25) / 2
Ah, our teacher has not talked about it, let's do it! I'm so worried!
Log (a) B = log (c) B / log (c) a (a ＞ 0, a ≠ 1, B ＞ 0, C ＞ 0, C ≠ 1) the logarithm of B with a as the base is equal to the logarithm of B with C as the base divided by the logarithm of a with C as the base
2lg2+lg25-lg10=______ ．
2 LG2 + lg25-lg10 = LG4 + lg25-lg10 = LG4 × 2510 = LG10 = 1, so the answer is 1
