Question 71721
<br>
Another path to the solution....<br>
{{{log(2,(x^log(2,(x))))=4}}}<br>
Rewrite that using {{{log((A^((B))))=B*log((A))}}}<br>
{{{log(2,(x))*log(2,(x))=4}}}
{{{(log(2,(x)))^2=4}}}<br>
{{{log(2,(x))=2}}} or {{{log(2,(x))=-2}}}<br>
{{{x=2^2=4}}} or {{{x=2^(-2)=1/4}}}<br>
ANSWERS: x=4 or x=1/4<br>
