Let us discuss a question whether -25 is a rational number or an irrational number? This topic is quite easier. It can be explained in the following way: First of all we should know about the meaning of rational and irrational numbers.

Today we will check if ‘0’ is a rational number or an irrational number. If we recall the definition of rational numbers, they are the numbers which can be expressed in form of p/q where p & q both are integers and q ≠ 0. Moreover, we know 0 can be written as 0/1, we observe that both 0 & 1 are integers and the denominator i.e. ‘1’ ≠ 0. So we conclude that ‘0’ is a rational number and not irrational.

Irrational number is an number that cannot be expressed as a fractions. It is not necessary that the sum of two irrational numbers is irrational , it can be rational. Assuming r is rational number and p is a irrational number, then r-p is irrational. in this p+(r-p)=r is irrational. From this equation we can say that an irrational can be written in different way as a sum of two irrational number. Now we say that sum the sum of two irrational be irrational then, it may also be possible.

Let us discuss in our session if -16 is an irrational number or a rational number. First of all we should know what is the exactly meaning of rational and irrational numbers. Initially we define what rational numbers are. Rational numbers are those numbers that can be written in the form of an integer divided by another integer.

The best way of understanding that negative of an irrational number is an irrational number or can irrational numbers be negative is mention below. Friends first we discuss about irrational number:- irrational number are number that can be represented by a fraction. Means they don’t have terminating or repeating decimal.

Firstly the idea of irrational numbers were discovered in the Pythagoras school, a great Greek mathematician who was founded the group of mathematicians and philosophers in the Italian port town of Cortona in the 6th century B.C.

Prove a number is Irrational? - To prove that a number is irrational, we first recall the definition of irrational number. The numbers which cannot be expressed in in form of p / q , where p q are integers and q 0. Moreover, the numb

We all know that rational and irrational numbers all together are called Real numbers. What are irrational numbers is the query which has been frequently asked by students so here is the answer. Any number ‘n’ is called irrational if it cannot be written in the form of rational number i.e. in form of p/q, where p & q are integers and q≠0. Moreover irrational numbers are the numbers which when expressed in the decimal form are non-terminating and non-repeating.

The best way of understanding how can we solve irrational number is given below. Friends First we discuss about irrational number:- An irrational number is any number that is real but not rational and cannot be expressed as a simple fraction or non repeating decimal. Most of irrational number the set of all rational number and take more space in column or decimal. Some Example of irrational numbers are:- 2, 5,6,7, ?3.14).

If we talk about geometry then, all gone through Pythagoras theorem. Without this theorem trigonometry one of the major branches of mathematics is not possible, because all the basic formulas of trigonometry are biased on Pythagoras theorem.

In the mathematical field an irrational numbers are the real numbers that can’t be expressed in a fraction form. In a simple meaning an irrational numbers cannot be represented as a rational form. Irrational numbers are those real value numbers that can’t be represented as terminating or repeating decimals.

Real numbers which cannot be written in (a/b) form are called as irrational numbers like √3, √5,√2 etc. Now, we discuss applications of irrational numbers.

Here, I am going to tell you the best way of understanding that root of 3 is an Irrational Number. So, we are assuming √3 is a rational number i.e √3=a/b equation (1) Where a and b are integers having no common factor (b≠0). On squaring both side, (√3)2= (a/b) 2 3= a2/b2 equation (2) 3b2=a2 equation (3) where a and b are both odd number and a/b reduce to smallest possible terms.

Let us first take any number say (4-√3). We check if it is rational or irrational. Let us assume that (4-√3) is a rational number. Then, 4 is rational , (4-√3) is rational. We also know that the difference of two rational numbers is also rational. So = (4-(4-√3) is rational. = 4-4+√3 is rational =√3 is rational. But we know that √3 is not a rational number, so it contradicts our assumption that (4-√3) is a rational number. So we conclude that (4-√3) is irrational number.
