DOUBT IN (B) PART:::
*****WHY IS AMGM WRONG IN B ? BY THAT WE GET ANS 16
BY EQUATING BOTH TERMS SINCE THEY ARE BOTH POSITIVEBUT ANS GIVEN IS 1
PLS EXPLAIN RIGHT METHOD AS WELL AS FLAW IN AMGM METHOD*****
ANS1
THANKS

@ABCDMAABCDMA
Something less than 2 raised to 4 can never be equal to something greater than 2 raised to 4 .....in am gm equality comes when both terms are equal ...but these two terms cannot be equal

@SanketBiradar
but they are surely equal at x=2 na
pls see oncealso pls show how ans is 1


Pls somebody solve the query

@ABCDMAABCDMA
I don't think 1 can be the answer.....see from here all terms are positive and greater than 16

@SanketBiradar ya this way I got the answer... But i am not understanding amgm method, if I were to solve it by amgm and since both are positive I equated them... What conceptual error here gave wrong ans?

please reply
