Simple Logarithmic question.

97 Views Asked by At

I was just wondering if i can do this.

Q. Solve $\log_{9}24=x $

$\implies9^x =24$

$\implies3^{2x}=2^3 3$

$\implies\log_3(3^{2x})= \log_3(2^3 3)$

$\implies2x=2 (3)^{1/3}$

$\implies x=3^{1/3} $

Is this actually correct or did i break some kind of log rule here? My answer appears to be out by 0.0038 compared to the book is that cause they used a calculator or is it just a fluke that my answer is so close?

Your method is incorrect as pointed out by Mufasa (sorry I didn't spot that earlier) but it's not the way I'd have done it anyway (and probably not how the book answer was obtained). This way is better:

$9^x = 24$

$\implies x\ln 9 = \ln 24$

$\implies x = \frac{\ln 24}{\ln 9} = 1.44639...$
