化简

0.000225

\frac{3}{200}

十进制

0.015

求解步骤

0.000225

0.000225 = \frac{9}{40000}

= \frac{9}{40000}

使用根式运算法则:

\frac{a}{b} = \frac{a}{b}, a \geq 0, b \geq 0

= \frac{9}{40000}

9 = 3

= \frac{3}{40000}

40000 = 200

= \frac{3}{200}

x^{2} - 10 x + 24 = 0

3 x - 2 (2 x + 3) = 5 - [2 x - 3 (4 - x)]

7 - (- 8) - x = 4 - (2 - 9)

9 v - 14 = 6 v - 2
