Question

помогите пожалуйста!!​

Answer 1

$1) \frac{a {}^{ \frac{4}{3} }(a {}^{ \frac{1}{3} } + a {}^{ \frac{2}{4} } )}{a {}^{ \frac{1}{4} } (a {}^{ \frac{3}{4} } + a {}^{ - \frac{1}{4} } } = a \frac{13}{12} \times \frac{(a {}^{ \frac{1}{3} } + a {}^{ \frac{2}{3} } )}{a {}^{ \frac{3}{4} } + a {}^{ - \frac{1}{4} } } = \frac{a {}^{ \frac{17}{12} } + a {}^{ \frac{7}{4} } }{a {}^{ \frac{3}{4} } + \frac{1}{a {}^{ \frac{1}{4} } } } = \frac{a {}^{ \frac{17}{12} } + a {}^{ \frac{7}{4} } }{ \frac{a + 1}{ a {}^{ \frac{1}{4} } } } = \frac{(a {}^{ \frac{17}{12} } + a {}^{ \frac{7}{4} } a {}^{ \frac{1}{4} } ) }{a + 1} = \frac{a {}^{ \frac{5}{3} } + a {}^{2} }{a + 1} = \frac{ \sqrt[3]{a {}^{5} } + a {}^{2} }{a + 1} = \frac{a \sqrt[3]{a {}^{2} } + a {}^{2} }{a + 1}$
