Question 769077
<br>
Algebraic expressions written in words are often ambiguous and open to different interpretations, as the other tutor indicated.<br>
Assuming this is a problem from a student learning basic rules of logarithms, the most likely interpretation of the expression to be evaluated is
{{{log(((sqrt(x))/y^2))}}}<br>
In that case, use basic logarithm rules to evaluate the expression.<br>
{{{log(((sqrt(x))/y^2))=log((((x)^(1/2))/y^2))=(1/2)log((x))-2log((y))=(1/2)(4)-2(3)=2-6=-4}}}<br>
