log \sqrt{x} - log \sqrt{5} =  \frac{1}{2}

Aplicando propiedades de potencia
log x^{\frac{1}{2}} - log 5^{ \frac{1}{2} } = 1/2

Aplicando propiedades de logarítmos
log (\frac{x}{5})^{\frac{1}{2}} = 1/2

 \frac{1}{2} log(\frac{x}{5}) =  \frac{1}{2}

 log\frac{x}{5} = \frac{1}{2}.2 = 1

 \frac{x}{5} = 10^{1}

x = 5x10

x = 50
