Logarithm question
Simplify 1/ logxy(xyz)+ 1/logyz(xyz)+1/ logzx(xyz)
Formula
log m to the base n =logm/logn.
= 1/(logxyz/log xy) + 1/(log xyz/log yz) + 1/(log xyz/log zx).
=log xy/log xyz +log yz/log xyz +log zx/log xyz.
=(1/log xyz). (logxy+logyz+log zx).
=(1/log xyz).(logxy.yz.zx).
=log(xyz)^2/logxyz.
= 2.logx.y.z/logx.y.z
= 2 , Answer.
