x^y-y^x=1
then x/y+y/x=?

• ans=2.5 ,x=2,y=1
• 8 years agoHelpfull: Yes(18) No(2)
• do yourself by using hit and trial ans is 2.17
  x=3, y=2
• 8 years agoHelpfull: Yes(3) No(5)
• 2^1 - 1^2 = 1
  so 2 + 1/2 = 5/2
  ans 2.5
• 8 years agoHelpfull: Yes(3) No(1)
• 0 ans.
  take it log on both sides then we got
  y logx=log1+xlogy
  log(x/y)=x/y
  similarly,, log(y/x)=y/x
  log(x/y*y/x)=log1=0 ans

• take x=3, y=2.
  3^2=9.
  2^3=8. then 9-8=1.
  x/y+y/x=3/2+2/3=2.167 (13/6)
