Question

помогите решить пожалуйста

Answer 1

$1.)( \frac{ \frac{3x}{x} + \frac{2}{x} }{ \frac{3x}{x} - \frac{4}{x} } ) {}^{ \frac{2x}{x} - \frac{7}{x} } = ( \frac{3 + 0}{3 - 0} ) {}^{2 - 0} = ( \frac{3}{3} ) {}^{2} = 1 {}^{2} = 1 \\ 2.) - 5 \times \frac{ \frac{1}{2 \sqrt{x} } }{ \sqrt{x {}^{2} } } + \frac{1}{1 + ( {x}^{2}) {}^{2} } \times 2x \\ - \frac{5}{2x \sqrt{x} } + \frac{2x}{1 + x {}^{4} } \\ 3.) \\ \frac{1}{3(x + 1)} + \frac{1}{ 15(x - 2)} + \frac{3}{5(x + 3)} dx \\ \frac{1}{3} \times ln( |x + 1| ) + \frac{1}{15} \times ln( |x - 2| ) + \frac{3}{5} \times ln( |x + 3| )$
