An irrational number is a type of real number which cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio. If N is irrational, then N is not equal to p/q where p and q are integers and q is not equal to 0. Example: √2, √3, √5, √11, √21, π (Pi) are all irrational. Q2.
π is an irrational number that has a value of 3.142…and is a never-ending and non-repeating number. √2 is an irrational number, as it cannot be simplified. 0.212112111…is a rational number as it is non-recurring and non-terminating.
Definition of Irrational Numbers. The set of real numbers that cannot be written in the form of \ (\frac {p} {q}\), where p and q are integers, is known as irrational numbers. The decimal expansion of an irrational number is neither terminating nor repeating.
The decimal expansion of rational numbers is either terminating or recurring. The decimal expansion of irrational numbers is non-terminating and non-recurring. 3. Rational numbers include perfect squares such as 4, 9, 16, 25, and so on. Irrational numbers include surds such as √2, √3, √5, √7 and so on. 4.

Rational Numbers. In Maths, a rational number is a type of real number, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number. Some of the examples of rational numbers are 1/2, 1/5, 3/4, and so on. The number “0” is also a rational number, as we can represent it in many forms ...
But √5 is an irrational number. Hence, we have arrived at a contradiction. ∵2√5 is an irrational number. Q. Fill in the blanks to complete the proof of 1+7√3 as an irrational number, provided √3 is an irrational number. Let’s assume 1+7√3 be a rational number. ⇒ 1+7√3= a b,b≠0.
Q. Prove that 2 + 3 is an irrational number, given that 3 is an irrational number.
Which is the smallest composite number? Prove that any positive odd integer is of the form 6x + 1, 6x + 3, or 6x + 5. Evaluate 2 + 3 × 6 – 5. What is the product of a non-zero rational number and an irrational number? Can every positive integer be represented as 4x + 2 (where x is an integer)? Real Numbers Class 9 and 10
