WebIrrational numbers are numbers that are not rational. Every integer happens to be a rational number. This is because each integer n can be written as n/1. For example 5 = 5/1. Therefore, 5 is a rational number and is not an irrational number. Question. Can we say that zero is an irrational number? Answer.

WebIn real numbers Class 9, the common concepts introduced include representing real numbers on a number line, operations on real numbers, properties of real numbers, and the law of exponents for real numbers. In Class 10, some advanced concepts related to real numbers are included. and the square root of 9 is 3; √9 = 3. Therefore, the number of irrational numbers between 2 and 3 are √ 5, √ 6, √ 7, and √ 8, as these are not perfect squares and cannot be simplified further. Similarly, you can also find irrational numbers, between any other two perfect square numbers.
