化简 sqrt(0.64)

解答

化简

0.64

\frac{4}{5}

十进制

0.8

求解步骤

0.64

0.64 = \frac{16}{25}

= \frac{16}{25}

使用根式运算法则:

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

= \frac{16}{25}

16 = 4

= \frac{4}{25}

25 = 5

= \frac{4}{5}

\frac{1}{3} + \frac{5 x}{6} > - \frac{5 x}{6} - \frac{1}{3}

x^{2} - 14 x + 51 = 0

f a c t or - 3 x^{2} + 2 x + 8

x^{2} + 3 x - 12 > 0

f a c t or 64 c z^{3} + 27 c x^{3}
