The solution
Detail solution
Given the equation
$$\log{\left(2 x + 1 \right)} = 0$$
$$\log{\left(2 x + 1 \right)} = 0$$
This equation is of the form:
By definition log
then
$$2 x + 1 = e^{\frac{0}{1}}$$
simplify
$$2 x + 1 = 1$$
$$2 x = 0$$
$$x = 0$$
$$\log{\left(2 x + 1 \right)} = 0$$
$$\log{\left(2 x + 1 \right)} = 0$$
This equation is of the form:
log(v)=p
By definition log
v=e^p
then
$$2 x + 1 = e^{\frac{0}{1}}$$
simplify
$$2 x + 1 = 1$$
$$2 x = 0$$
$$x = 0$$
