Answer 1

$\sqrt[4]{ \frac{16a ^{8} b ^{4} }{0.0001c ^{12} } } = \frac{2a ^{2}b }{0.1c ^{3} } \\ \\ \frac{2* \frac{1}{9}* \frac{1}{10} }{ \frac{1}{10}* \frac{8}{27} } = \frac{ \frac{2}{9*10} }{ \frac{8}{10*27} } = \frac{ \frac{1}{9*5} }{ \frac{4}{5*27} } = \\ \\ = \frac{1}{42} : \frac{4}{135} = \frac{42*4}{135} = \frac{168}{135} =1 \frac{33}{135}$

$y= \frac{ \sqrt{x} }{ x^{2} -3} \\ \sqrt{x} \geq 0\\x \geq 0 \\ \\ x^{2} \neq 3\\ \\ x \neq +- \sqrt{3} \\ \\ Otviet:C)$
