\[\log_{4} x=1+\log_{2} 2x, x>0\]

yeah ... solve for x.

use this property of log \[ \log_a b = \frac{\log_kb}{\log_k a}\]

i still dont get it sorry
experimentX
  • experimentX
sorry ... error there \[ \log_4x = \frac{\log_2k}{\log_24} = \frac{\log_2k}{2} \]
experimentX
  • experimentX
Oops ... error again, that k is supposed to be x

if you know other few properties of log then it's should be easy for you!!
experimentX
  • experimentX
\[ \frac{\log_2x}{2} = \log_22 + \log_22x\] \[ \implies \log_2x = 2\log_22 + 2\log_22x \] \[ \implies \log_2x = \log_22^2 + \log_2(2x)^2 \] \[ \implies \log_2x = \log_2(2^2*(2x)^2) \] \[ \implies x = 2^2*(2x)^2 \]

\[ \implies x = \frac{1}{16} \]
