Помогите пж по алгебре

Answer 1

${x}^{5} times {x}^{ - 8} = {x}^{ - 3} \ {x}^{ - 3} div {x}^{ - 2} = {x}^{ - 1} \ { frac{1}{3} }^{ - 1} = 3$
$frac{ sqrt{12} }{ sqrt{50} times sqrt{6} } = frac{2 sqrt{3} }{5 sqrt{2} times sqrt{2 } times sqrt{3} } = frac{2}{10} = frac{1}{5} = 0.2$
$frac{x(x - 2)}{(2 - x)(2 + x)} = - frac{x}{2 + x}$
