Помогите пожалуйста!

Решите задачу:

$1)\quady=log_3(log_{0,5}x)\\\\OOF:\; \; \left \{ {{x\ \textgreater \ 0} \atop {log_{0,5}x\ \textgreater \ 0}} \right. \; \left \{ {{x\ \textgreater \ 0} \atop {0\ \textless \ x\ \textless \ 1}} \right. \quad \to \quad x\in (0,1)\\\\2)\quad y= \frac{3x+2}{\sqrt{6x-5-x^2}} \\\\OOF:\; \; 6x-5-x^2\ \textgreater \ 0\; \; \to \; \; x^2-6x+5\ \textless \ 0\\\\x_1=1\; ,\; \; x_2=5\quad +++(1)---(5)+++\\\\x\in (1,5)\\\\3)\quad y= \frac{x}{2+4sinx} \\\\OOF:\; \; 2+4sinx\ne 0\\\\sinx\ne - \frac{1}{2} \\\\x\ne (-1)^{n}\cdot(-\frac{ \pi }{6})+\pi n,\; n\in Z \\ \\ x\ne (-1)^{n+1}\cdot \frac{\pi}{6}+\pi n,\; n\in Z$
