log(4x+3)=y la ecuación
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
Solución detallada
Tenemos la ecuación
$$\log{\left(4 x + 3 \right)} = y$$
$$\log{\left(4 x + 3 \right)} = y$$
Es la ecuación de la forma:
log(v)=p
Por definición log
v=e^p
entonces
$$4 x + 3 = e^{\frac{y}{1}}$$
simplificamos
$$4 x + 3 = e^{y}$$
$$4 x = e^{y} - 3$$
$$x = \frac{e^{y}}{4} - \frac{3}{4}$$
