①任意取一个在 根号2 附近的数，为了方便运算我们取最接近根号2的整数1，并记f (1)=1。 ③根据上面的递推式算出数列f (n)的后面几项，算到f (5)就很接近根号2了（可以算得f (4)=577/408≈1.414215686…，f (5)=1.414213562…) 当然估计根号2的方法不止以上两种，题主有兴趣还可以从根号x的 级数展开 考虑。 但是迭代法一般是算得最快的，因为上面那个递推数列收敛得很快。 知乎，中文互联网高质量的问答社区和创作者聚集的原创内容平台，于 2011 年 1 月 …

2017年9月11日 · 一个数的0.5次方可以通过计算该数的平方根来得到。对于整数2来说，它的0.5次方等于其平方根，即2的0.5次方等于√2，约等于1.414。

That's it! 0.5 as a fraction in it's simplest form is equal to 1/2 (½). This online Decimal to Fraction converter is a tool that can help you convert any decimal number into its fractional form quickly and easily. For example, it can help you find out what is 0.5 as a fraction in simplest form? (The answer is: 1/2 (½)).

指的是精确度 0.2代表额定一次电流额定二次负荷时误差限值为0.2%。 一般来说 测量选用0.5 计量选用0.2（S）；S级的意义在于当一次电流很小时普通CT的误差很大，二次基本不输出，这样导致小电流时计量误差大。

2的2.5次方怎么算结果为：5.656解题过程如下：利用公式：a^(m+n)=(a^m)×(a^b)设a为某数，n为正整数，a的n次方表示为aⁿ，表示n个a连乘所得之结果，如2⁴=2×2×2×2=16原式=2^2.5=(2^2)×(2^0.5)=4×1.14

The number 2 - 0.5 is how many times the number 1 - 0.5? (A) 2 (B) 2.5 (C) 3 (D) 3.5 (E) 4 From the stem we can set up the following equation: \((2-0.5)=x*(1-0.5)\); \(1.5=x*0.5\); \(x=3\). Answer: C.

Raise 0.5 0.5 to the power of 2 2. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

2022年2月28日 · First, let's do 3 times 0.5, which we'll treat as 0.5 + 0.5 + 0.5. But instead of thinking of it happening all at once, imagine we take 3 seconds, and in the first second we move from 0 to 0.5, in the second second we move from 0.5 to 1.0, and in the third second we move from 1.0 to 1.5, and then we're finished and see our answer is 1.5.
