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