I'm having trouble solving a logarithmic equation.  Here's the equation: logx^2=(logx)^2 Does someone have a suggestion for how I might approach the problem?  Thanks.

logx^2=(logx)^2Use rule of logs:2log(x)=(logx)^2Now use substitution by letting t=logx2t=t^2 ort^2-2t=0t(t-2)=0So t=0 or t=2Now go back to the substitution:log(x)=0 or log(x)=2Now just solve for xHope that helps
