log(3base)N +log(9base)N =
a. 1
b. 9
c. 111
d .333

• take n=729
  log(3base)729+log(9base)729
  6log(3base)3+3log(9base)9
  6*1+3*1=9
  so,only one value is possible for whole number...coz in question n is 3 digit number gvn.

• i think it should be 9 because i find two values of n so it is impossible that ans should be 1 so 9 will be the ans
• 9 years agoHelpfull: Yes(7) No(0)
• 1
  only N=9^3
• 9 years agoHelpfull: Yes(4) No(1)
• The ans. will be 9.
• 9 years agoHelpfull: Yes(4) No(2)
• bhaiyon pehle yeh batao ki hum logon ko n ki value nikalni thi ya pure term ki
• 9 years agoHelpfull: Yes(4) No(1)
• ans.1
  actually we have two posiblelites243,729
  if we take 243 then ans is 5+2.5=7.5 it is not whole number,so we hav eonly one posibility.
  ans will be whole number clearly mention in quetion.

• 729= 3^6 ,9^3
  6log3_3 + 3log9-9= 6+3
• 9 years agoHelpfull: Yes(3) No(2)
• ans will be 1
