⁶log 45 = ³log 45 : ³log 6
⁶log 45 = (³log (3² x 5)) : (³log (3 x 2))
⁶log 45 = (³log 3² + ³log 5) : (³log 3 + ³log 2)
⁶log 45 = ( 2 + b) : ( 1 + 1/a)
⁶log 45 = (b + 2) : (a + 1)/a
⁶log 45 = (b + 2) x a/(a + 1)
⁶log 45 = (ab + 2a) / (a + 1)

6log45 = 3log45 / 3log6
= (3log3.3.5) / (3log2.3)
= (3log3 + 3log3 + 3log5) / (3log2 + 3log3)
= (1 + 1 + b) / (1/a + 1) . a/a
= a(2 + b) / (1 + a)
