Answer:
Let :
K = [(yz)^(log y - log z)] • [(zx)^(log z - log x)] • [(xy)^(log x - log y)]
Then :
log K = (log y - log z)· log (yz) + ... two similar terms
. . . . = (log y - log z)·(log y + log z) + ... two similar terms
. . . . = [ (log y)² - (log z)² ] + [ (log z)² - (log x)² ] + [ (log x)² - (log y)² ]
. . . . = 0.
Since : log K = 0,
Hence : K = 1.
Thus, the result is proved.
