  • Question
  • For x?N, x>1 , and p=logxx+1 , q=logx+1x+2 then which one of the following is correct?


  • Options
  • A. p < q
  • B. p = q
  • C. p > q
  • D. can't be determined

  • Correct Answer
  • p > q 

    Explanation

    k l > k + 1 l + 1  for (k,l) > 0 and  k > l 

     

     

     

    Let     k = x+1    and   l = x

     

     

     

    Therefore,  x + 1 x > ( x + 1 ) + 1 ( x ) + 1

     

     

     

     (x + 1) > x

     

     

     

    Therefore,  log ( x + 1 ) log ( x ) > log ( x + 2 ) log ( x + 1 )

     

     

     

    ? log x x + 1   > log x + 1 x + 2
