Answer 1

Answer:

Step-by-step explanation:

log (a/b) = log a - log b

log(ab) = log a +log b

=log(x^2/yz) + log(y^2/zx) + log(z^2/xy)

=log(x^2) - log(yz) +log(y^2) - log zx +log (z^2) - log xy

=2log x -log y -log z +2log y -log z -log x + 2log z- log x-log y

=2log x +2log y+2log z- 2log x-2log y-2log z

=0
