what are irretional numbers? give a few examples?

Hii

Irrational number is a number which cannot be expressed into fraction p/q , where p and q are integers. Irrational numbers have decimal expansions that neither can become be periodic nor does it terminate.

Few of examples are like- square root of 3

The value of it is 1.73205080...

It can't be terminated nor it becomes periodic after some time like 1.323232 where 32 is periodic. And also it 1.732.... cannot be expressed as fractions

Hello there!

Greetings!

Irrational Number are real numbers that cannot be written as a simple fraction and have decimal expansions that neither terminate nor become periodic. For example pi ( (3.1415...) is an irrational number as it has an infinite number of digits after the decimal point. In the same way 3^1/2 = 1.732..... is irrational as its decimal expansion neither terminates  nor become periodic.

Thankyou

Any number that cannot be expressed as a rational of 2 integers is called a irrational number. If I take Pi, the value of Pi is 3.14159.....So the value of Pi doesn't stop at 3.14 but it goes beyond. So this is a irrational number. And if you look at the square root value of 2. It goes beyond 1.41421356...... So square root of 2 is an irrational number. But if you look at square root of 9, it is 3. It is exactly 3. And so it is a rational number. Square root value of 3, 5, 7, 10 are also examples of irrational numbers.
