Question

Логарифмы:
1. log(3 (2)) - log(3 (2/9))=
2. (1/4)^log(1/2 (3))=
3. log(4 (16)) * log(1/2 (1/4))=

Answer 1

$1) log_32 - log_3 frac{2}{9} =log_3 frac{2}{ frac{2}{9} } =log_39=2\ 2) frac{1}{4} ^{log_ frac{1}{2} 3}= frac{1}{4} ^{log_ frac{1}{4} 9}=9\ 3)log_416*log_ frac{1}{2} frac{1}{4} =2*2=4$
