The solution
Detail solution
Given the equation
$$x \log{\left(y \right)} = 0$$
$$x \log{\left(y \right)} = 0$$
Let's divide both parts of the equation by the multiplier of log =x
$$\log{\left(y \right)} = 0$$
This equation is of the form:
By definition log
then
$$y = e^{\frac{0}{x}}$$
simplify
$$y = 1$$
$$x \log{\left(y \right)} = 0$$
$$x \log{\left(y \right)} = 0$$
Let's divide both parts of the equation by the multiplier of log =x
$$\log{\left(y \right)} = 0$$
This equation is of the form:
log(v)=p
By definition log
v=e^p
then
$$y = e^{\frac{0}{x}}$$
simplify
$$y = 1$$
