Answer 1

а)

$5 {x}^{5} - {x}^{4} =0 \\ 5x - 1 = 0 \\ 5x = 1 \\ x = \frac{1}{5} = 0.2$

б)

${x}^{4} + {x}^{3} = 0 \\ x + 1 = 0 \\ x = - 1$

в)

$10 {x}^{6} - 3 {x}^{5} =0 \\ 10x - 3 = 0 \\ 10 x= 3 \\ x = \frac{3}{10 } = 0.3$

г)

$3 {x}^{3} - 12x = 0 \\ {x}^{2} - 4 = 0 \\ {x}^{2} = 4 \\ x1 = 2 \\ x2 = - 2$

д)

$4 {x}^{4} - 9 {x}^{2} = 0 \\ 4 {x}^{2} - 9 = 0 \\ 4 {x}^{2} = 9 \\ {x}^{2} = \frac{9}{4} \\ x1 = \frac{3}{2 } = 1.5 \\ x2 = - \frac{3}{2} = - 1.5$

е)

${x}^{5} - {x}^{3} = 0 \\ {x}^{2} - 1 = 0 \\ {x}^{2} = 1 \\ x1 = 1 \\ x2 = - 1$
