- do yourself by using hit and trial ans is 2.17
x=3, y=2 - 9 years agoHelpfull: Yes(3) No(5)
- 2^1 - 1^2 = 1
so 2 + 1/2 = 5/2
ans 2.5 - 9 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 - 9 years agoHelpfull: Yes(3) No(6)
- 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) - 9 years agoHelpfull: Yes(2) No(0)
