Answer 1

$\sqrt{ \frac{ \frac{1}{3} - \frac{1}{4} }{ \frac{4}{3} + \frac{3}{4} } } = \\ \sqrt{ \frac{ \frac{4}{12} - \frac{3}{12} }{ \frac{16}{12} + \frac{9}{12} } } = \\ \sqrt{ \frac{ \frac{1}{12} }{ \frac{25}{12} } } = \\ \sqrt{ \frac{1}{12} \div \frac{25}{12} } = \\ \sqrt{ \frac{1}{12} \times \frac{12}{25} } = \\ \sqrt{ \frac{1}{25} } = \\ \frac{1}{5}$
