Question

Рещиет пожалуйста 5 не надо

Answer 1

Ответ:

$1) \frac{24}{ {3}^{ log_{3}(2) } } = \frac{24}{2} = 12$

$2) log_{0.2}(40) - log_{0.2}(8) = log_{0.2}( \frac{40}{8} ) = log_{0.2}(5) = log_{ \frac{1}{5} }(5) = - 1$

$3) log_{3}(x) = 4 \\ x = {3}^{4} \\ x = 81$

$4)4 log_{0.1}(x) = log_{0.1}(2) + log_{0.1}(8) \\ log_{0.1}( {x}^{4} ) = log_{0.1}(2 \times 8) \\ log_{0.1}( {x}^{4} ) = log_{0.1}(16) \\ {x}^{4} = 16 \\ x = + - 2$

$6) {32}^{2x + 5} = {8}^{x - 1} \\ {2}^{5(2x + 5)} = {2}^{3(x - 1)} \\ 10x + 25 = 3x - 3 \\ 7x = - 28 \\ x = - 4$
