求解步骤

\frac{2}{5} \cdot \frac{2}{10}

对数字约分

\frac{2}{10} = \frac{1}{5}

= \frac{2}{5} \cdot \frac{1}{5}

\frac{2}{5} \cdot \frac{1}{5} = \frac{2}{25}

= \frac{2}{25}

h^{2} + 30 h + 200 = 0

8 x^{2} - x + 4 = 0

\frac{a + 13}{10} - \frac{2 a}{5} = \frac{3 - a}{15} + \frac{a}{2}

∣ 4 (x - 1) + 10 ∣ \leq 14
