Answer 1

Ответ:

${2}^{x} = \frac{4}{ \sqrt[3]{64} } \\ {2}^{x} = \frac{4}{ \sqrt[3]{ {4}^{3} } } \\ {2}^{x} = \frac{4}{4} \\ {2}^{x} = 1 \\ {2}^{x} = {2}^{0 } \\ x = 0$

$\frac{ {2}^{x} }{ {3}^{x} } = \frac{9}{4} \\ {( \frac{2}{3}) }^{x} = {( \frac{3}{2}) }^{2} \\ {( \frac{2}{3}) }^{x} = {( \frac{2}{3} )}^{ - 2} \\ x = - 2$
