Question

помогите у меня не выходит ответ!!!(

Answer 1

$frac{ {n}^{2} }{ {n}^{2} - {m}^{2} } = 12 \ \ {n}^{2} = 12( {n}^{2} - {m}^{2} ) \ frac{ {n}^{2} - {m }^{2} }{ {n}^{2} } = frac{1}{12} \ \ 1 - frac{ {m}^{2} }{ {n}^{2} } = frac{1}{12} \ \ frac{ {m}^{2} }{ {n}^{2} } = frac{11}{12} \ \ frac{ {n}^{2} }{ {m}^{2} } = frac{12}{11}$

$frac{22}{x} = frac{ {m}^{2} }{ {n}^{2} - {m}^{2} } \ \ {m}^{2} x = 22( {n}^{2} - {m}^{2} ) \ \ frac{ {n}^{2} - {m}^{2} }{ {m}^{2} } = frac{x}{22} \ \ frac{ {n}^{2} }{ {m}^{2} } - 1 = frac{x}{22 } \ \ frac{12}{11} - 1 = frac{x}{22} \ \ frac{1}{11} = frac{x}{22} \ \ x = frac{22}{11} = 2$
