Объяснение:

$11. log_{2}(5) \times log_{5}(8) = \frac{1}{ log_{5}(2) } \times 3 log_{5}(2) = 3 \\ 12. log_{2}(3.2) + log_{2}(5) = log_{2}(3.2 + 5) = \\ = log_{2}(8.2) \\ 13.(1 - log_{6}54)(1 - log_{9}54) = (1 - log_{6}(9) - 1) \times \\ \times (1 - log_{9}(6) - 1) = \frac{1}{ log_{9}(6) } \times log_{9}(6) = 1 \\ 14.10 log_{6}( \sqrt[4]{6} ) = \frac{10}{4} log_{6}(6) = 2\frac{1}{2} \\ 15. log_{ \sqrt[5]{12} }(12) = 5 \\ 16. \frac{ log_{2}(48) }{3 + log_{2}(6) } = \frac{ log_{2}(8) + log_{2}(6) }{ log_{2}(8) + log_{2}(6) } = 1$
