log 625 base 25 -log 961 base 31 + log 841 base 29 is

• Ans is 2-2+2=2
  log 625 base25-log 961 base 31+ log 841 base 29
  log 25^2 base 25+ log 31^2 base 31 + log 29^2 base 29.
  So 2-2+2=2

• Ans:- 2
  
  Solution:-
  
  log y base b = x
  b^x = y
  
  log 625 base 25 = 2
  log 961 base 31 = 2
  log 841 base 29 = 2
  
  log 625 base25-log 961 base 31+ log 841 base 29
  So
  =2-2+2
  =2

• let log 625 base 25=x
  x=2;
  log 961 base 31=y
  y=2;
  log 841 base 29=z
  z=2;
  x-y+z=2;

• here we know that log a base a=1
  
  so log 25^2 base 25 -log 31^2 + log 29^2
  2log 25 base 25 -2 log 31 base 31 + 2 log 29 base 29
  2-2+2=2 answer
