LHS= x^(log y/z).y^(log z/x).z^(logx/y)
= Antilog * log [x^(log y/z).y^(log z/x).z^(logx/y)]
= Antilog * [logx (logy - logz + logy (logz - logx) + logz (logx - logy)]
= Antilog 0
= 1
= Antilog * log [x^(log y/z).y^(log z/x).z^(logx/y)]
= Antilog * [logx (logy - logz + logy (logz - logx) + logz (logx - logy)]
= Antilog 0
= 1
