Question

ABC are real numbers greater than 1 . if loga X=24, log bX=40 and log abcX =12 then logcX equals is

Answer 1

it's easy 

given                logₐ x = 24  ⇒ log x / log a = 24
                       =  log a / log x = 1/24

similarly           log b / log x = 1/40

and               log abc / log x = 1/ 12  =  log a + log b + log c / log x = 1/12

               = log c / log x = 1/12 - 1/40 - 1/24 = 1/60

                now    log x / log c = 60     =     log base(c)  x = 60

hope u'll get it..................doubts? ask !
