$8)\; \; y=\frac{\sqrt{x+15}}{|x|-8}\\\\OOF:\; \; \left \{ {{x+15\geq 0} \atop {|x|-8\ne 0}} \right.\; \; \left \{ {{x\geq -15} \atop {|x|\ne 8}} \right.\; \; \left \{ {{x\geq -15} \atop {x\ne \pm 8}} \right.\; \; \Rightarrow \\\\x\in [-15;-8)\cup (-8;8)\cup (8;+\infty )$

$8b)\; \; y=\sqrt{x-4}(x^2-36)^{-2}\; \; ,\; \; \; y=\frac{\sqrt{x-4}}{(x-6)^2(x+6)^2}\\\\OOF:\; \; \left \{ {{x-4\geq 0\qquad \; \; } \atop {x-6\ne 0\; ,\; x+6\ne 0}} \right.\; \; \left \{ {{x\geq 4\qquad \quad } \atop {x\ne -6\; ,\; x\ne 6}} \right. \\\\x\in [\, 4;6)\cup (6,+\infty )$
