[tex]1) \frac{1}{2} x + \frac{3}{2} x = ( \frac{1}{2} + \frac{3}{2} )x = \frac{4}{2}x = 2x [/tex]
[tex]2) \frac{3}{10} x + \frac{1}{10} x + \frac{5}{10} x = ( \frac{3}{10} + \frac{1}{10} + \frac{5}{10} ) x= \frac{9}{10} x[/tex]
[tex]3) \frac{4}{5} {x}^{2} + \frac{7}{5} {x}^{2} + \frac{1}{5} {x}^{2} = ( \frac{4}{5} + \frac{7}{5} + \frac{1}{5} ) {x }^{2} = \frac{12}{5} {x}^{2} [/tex]
[tex]4) \frac{3}{7} {x}^{2} + \frac{2}{7} {x}^{2} - \frac{1}{7} {x}^{2} = ( \frac{3}{7} + \frac{2}{7} - \frac{1}{7} ) {x}^{2} = \frac{4}{7} {x}^{2} [/tex]
[tex]5) \frac{16}{8} {x}^{5} + \frac{3}{8} {x}^{5} - \frac{7}{8} {x}^{5} = ( \frac{16}{8} + \frac{3}{8} - \frac{7}{8} ) {x}^{5} = \frac{12}{8} {x}^{5} = \frac{3}{2} {x}^{5} [/tex]
