Solve the following logarithmic equations.<br> ln(32x^2) − 3 ln(2) = 3
Kazeer [188]

Answer:

x=\pm \frac{\sqrt{e^{3} } }{2}

Step-by-step explanation:

Rewrite the equation using the next propierties:

log(\frac{1}{x} )=-log(x)

ylog(x)=log(x^{y} )

log(x*y)=log(x)+log(y)

ln(32x^{2} )-ln(2^{3})=3\\ ln(32x^{2} )+ln(\frac{1}{2^{3} } )=3\\ln(\frac{32x^{2} }{8})=3\\ ln(4x^{2} )=3

Cancel logarithms by taking exp of both sides:

e^{ln(4x^{2}) } =e^{3} \\4x^{2} =e^{3}

Divide both sides by 4:

x^{2} =\frac{e^{3} }{4}

Take the square root of both sides:

x=\pm \sqrt{\frac{e^{3} }{4} } =\pm \frac{\sqrt{e^{3} } }{2}
