Question

решите умоляяяяяяяяяяю

Answer 1

$\frac{ | {x}^{5} | }{4 | {y}^{3} | } = \frac{ {x}^{5} }{4 {y}^{3} }$
$11 | {x}^{8} {y}^{5} | =- 11 {x}^{8} {y}^{5}$

Answer 2

$1)\; \; a<0\; ,\; \; b<0\\\\\sqrt{\frac{a^{10}}{16b^6}}=\frac{|a|^5}{4|b|^3}=\frac{(-a)^5}{4\, (-b)^3}=\frac{-a^5}{-4b^3}=\frac{a^5}{4b^3}\\\\2)\; \; a>0,b<0\\\\\sqrt{121\, a^{16}\, b^{10}}=11\cdot |a|^8\cdot |b|^5=11\cdot a^8\cdot (-b)^3=-11a^8b^3$
