找出 3 到 4 之间的无理数
不能表示为简单分数的实数称为无理数。它不能像 p/q 这样的比率来表示,其中 p 和 q 都是整数,q≠0。无理数是任何不是有理数的数。无理数可以用小数表示,但不能用分数表示,这意味着它们不能表示为两个整数的比率。在小数点之后,无理数有无限数量的非重复数字。
无理数的十进制展开既不结束也不重复。无理数的定义是一个没有比率或无法说明比率的数,即除了使用根之外不能以任何其他方式表示的数。换句话说,无理数不能表示为两个整数的比率。
无理数的例子
√2、√3、√5 等是无理数的一些例子,因为它们不能以 p ⁄ q 的形式表示。欧拉数、黄金比例、π等也是无理数的一些例子。 1/0、2/0、3/0 等等都是非理性的,因为它们给了我们无限的价值。
找出 3 到 4 之间的无理数
解决方案:
Irrational numbers are real numbers that cannot be written in the form p/q, where p and q are integers and q≠0. For instance, √2 and √3 and so on are irrational. A rational number is any number that can be written in the form of p/q, where p and q are both integers and q≠0.
Here, the given numbers are 3 and 4. There can be an infinite number of irrational numbers between these numbers. The numbers between the squares of 3 and 4, i.e., between 9 and 16 are 10, 11, …14, 15. The square root of any of these numbers is always an irrational number. The square root of 10, i.e., √10 is an irrational number that lies between 3 and 4.
