Помогите пожалуйста с математикой :(

Answer 1

Ответ:

$9)( \frac{1}{36} ) {}^{1.25x - 2} = 6 \\ 6 {}^{ - 2.5x + 4} = 6 {}^{1} \\ - 2.5x + 4 = 1 \\ - 2.5x = 1 - 4 \\ - 2.5x = - 3 \\ x = 1.2 \\ 11)( \frac{1}{16} ) {}^{0.5x + 1} = 8 \\ 2 {}^{ - 2x - 4} = 2 {}^{3} \\ - 2x - 4 = 3 \\ - 2x = 3 + 4 \\ - 2x = 7 \\ x = - \frac{7}{2} \\ x = - 3.5$
