求解步骤

1 - (\frac{2}{5})^{8}

(\frac{2}{5})^{8} = \frac{256}{390625}

= 1 - \frac{256}{390625}

1 - \frac{256}{390625} = \frac{390369}{390625}

= \frac{390369}{390625}

4 x^{2} = 12 x - 7

x^{2} + 11 x = - 24

- 6 m \leq - 36 and m + 24 \leq 20

- p + 50 = 3 p - 30

\frac{x - 6}{5} = \frac{x + 1}{6}
