Logarytmy

Oblicz:
a)  log_{3} 4,5+ log_{3}2

b)log2000+log \frac{1}{2}

c) log x_{2}7- log_{2} 56

d)log_{7} 14-log_{7} 2 \sqrt{7}

Znajdź liczby a,b i c spełniające warunki:
a)log _{9} \sqrt{3}=a\\  log _{b} = \frac{1}{4}\\ log _{ \sqrt{3} } c=- \frac{1}{2}

I jeśli można to proszę o wytłumaczenie :)
