If x, y, z > 0 and x ≠ 1, y ≠ 1, z ≠ 1 such that log x/y−z =log y/z−x =log z/x−ythen prove thatx^xy^y z^z = 1.​

Answer»

Answer:

We have,  

​  

 

1+x

1

1

​  

 

1

1+y

1

​  

 

1

1

1+z

​  

 

​  

=0  

⇒  

​  

 

x

0

1

​  

 

−y

y

1

​  

 

0

−z

1+z

​  

 

​  

=0,  use R  

1

​  

→R  

1

​  

−R  

2

​  

 and R  

2

​  

→R  

2

​  

−R  

3

​  

 

Now EXPAND along FIRST row,

⇒x[y(1+z)+z]+y(0+z)=0

⇒xy(1+z)+xz+yz=0

⇒xy+yz+zx=−xyz

⇒x  

−1

+y  

−1

+z  

−1

=−1, divide both SIDES by xyz
