Answer 1

2

Пошаговое объяснение: log₂2=1

=log₂24*log₂48-log₂96*log₂12=log₂(12*2)*log₂48-log₂(48*2)*log₂12= (log₂12+log₂2)*log₂48-(log₂48+log₂2)*log₂12=log₂12*log₂48+log₂48-(log₂48*log₂12+log₂12)=log₂(12*48)+log₂48-log₂(12*48)-log₂12= log₂48-log₂12=  log₂48/12= log₂4=2

Answer 2

ответ: 2

$\frac{log_{2}{24}}{log_{48}{2}}-\frac{log_2{96}}{log_{12}{2}} = \frac{log_{2}{24}\times log_{12}{2} - log_2{96} \times log_{48}{2}}{log_{48}{2}\times log_{12}{2}} = \frac{log_{12}{24}\times log_{2}{2} - log_{48}{96} \times log_{2}{2}}{log_{48}{2}\times log_{12}{2}} = \\\\\frac{log_{12}{2} - log_{48}{2}}{log_{48}{2}\times log_{12}{2}} = log_2{48}-log_{2}{12} =log_2{4}=2$
