^ = pangkat

(log √6) : log 21 = (³log (2 . 3)^(1/2)) / (³log (7 . 3))
                          = (1/2 . (³log 2 + ³log 3)) / (³log 7 + ³log 3)
                          = (1/2 . (1/a + 1)) / (b + 1)
                          = (1/2 . (1 + a)/a) / (b + 1)
                          = (a + 1) / (2ab + 2a)
