How to solve Irrational Numbers How to solve Irrational Numbers
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). The square root of any prime number is irrational. Irrational number cannot be obtained by dividing one integer by another. So -1/3=0.333 is not a irrational because it is obtained by the ratio of two integer. 1 and 3. Irrational number cant have a finite decimal expression. Now, we discuss on some equation to solve the irrational number. We assuming that 3 is an rational number i.e 3=a/b equation Know More About Worksheet on Scientific Notation and Rational Number

(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. It is not possible that a and b are even because if a and b are even one can always be divided by 2 as we assume a/b is an rational numbers a=2m+1 Assuming a and b are odd b=2n+1 by putting the value of a and b in eq 3 : 3(2n+1)2= (2m+1)2 3(4n2+1+4n)= (2m2+1+4m) 12n2+3+12n=4m2+1+4m 12n2+12n+2=4m2+4m 6n2+6n+1=2m2+2m 6n2+6n+1=2(m2+n) In this equation all the value of m is always odd and the value of n is always n for all values s so this equation has no solution. Our assumption a and b are odd in invalid so we can say that root of 3 is an irrational number. In above articles we discuss about how to solve irrational numbers. What are irrational Numbers Irrational numbers are the numbers which are not rational numbers. In other words we can say that any number that cannot be expressed in the form of p/q are termed as irrational numbers. If any floating point number (that is a number that has an integer part as well as an decimal part is termed as floating point number.) cannot expressed as the ratio of two integers that floating point number is termed as irrational numbers. Let us take some of the examples of Irrational numbers Now if we take the value of “ pi (π ) “ that is π = 3.1415926535897932384626433832795 This value of π is Read More About Rational Numbers Properties Worksheets

impossible to express as the simple ratio of two numbers or two integers instead. Thus the value of π is an irrational number. Let us take some more examples to clearly get an image about the irrational numbers Let us take a value 3.2. Now 3.2 is not an irrational number, it is a rational number as 3.2 can be expressed as a ratio of two integers that is A square root of every non perfect square is an irrational number and similarly, a cube root of non-perfect cube is also an example of the irrational number. When we multiply any two irrational numbers and the result is rational number, then each of these irrational numbers is called rationalizing factor of the other one. Here is a general irrational number which is frequently used in mathematics. “Pi” is a best example of an irrational number. The value of 'pi' is solved to over one million decimal places and still there is no pattern found.
