解析 【解析】先将432化成为正$$ 3 \times 1 4 4 $$数的形式,利用二次 根式的化简求解即可. $$ \sqrt { 4 3 2 } = \sqrt { 1 4 4 \times 3 } = \sqrt { 1 4 4 } \times \sqrt { 3 } = 1 2 \sqrt { 3 } $$. 故答案为:12$$ \sqrt { 3 } $$2. ...
【解答】∵$$ 3 = \sqrt { 1 8 } , 2 = \sqrt { 1 2 } , 1 8 > 1 2 , $$ ∴$$ . > \sqrt { 1 2 } $$,即$$ 3 > 2 \sqrt { 3 } $$ 【点评】本题考查的是实数的大小比较,熟知正数 比较大小的法则是解答此题的关键. ...

如需要得到算术平方根中的负数值,则应该在sqrt函数前添加负号。 2.sqrt函数的参数必须是非负数值,如果是负数值,则输出会报错,即数值无效;如果参数是未定义的非数字变量,则按回车后也会报错,即变量名有误。 3.sqrt函数的计算精度与C语言设置的精度有关,可以通过设置更改精度。 有关sqrt函数但使用方法今天就介绍到...

What is [−3×−3]? https://www.quora.com/What-is-sqrt-3-times-sqrt-3 For solving this question you must need a brief idea regarding complex variable. i.e. (√-1)=i or i^2= -1 Where i is known as iota or we can also say that it is a imaginary part. Now for solution...
已知理想气体状态方程pV=NkT ,其中N表示体积V中气体分子总数,k是玻尔兹常量,在求气体分子方均根速率v时候,sqrt(v^2)=sqrt(3kT/m)=sqrt(3RT/M),这里sqrt是开根号的意思,R是普适气体常量,第二项消去k后,分母不是MN吗,为何只剩一个M?N去哪了参考pV=(mRT)/M=NkT M是气体摩尔质量,m是气体的质量 扫码...
