show that 5 minus 2 root 3 is an irrational number Prove that 5 2 3 is an irrational number Prove that 5 2 3 is an irrational number Solution Verified by Toppr
In this video I use the method of contradiction to prove that 5 2 root 3 is an irrational number in this method first we assume that the given irrational Let us assume that 5 3 2 is a rational number with p and q as co prime integers and q 0 5 3 2 p q 3 2 p q 5 2 p 5q 3q p 5q 3q is a rational number However we know that 2 is an irrational number This leads to the contradiction that 5 3 2 is an irrational number

We have to prove 5 3 is irrational Let us assume the opposite i e 5 is rational Hence 5 3 can be written in the form where a and b b 0 are co prime no common factor other than 1 Hence 5 3 5 We will use the contradiction method to show that 5 3 is an irrational number Let us assume that 5 3 is a rational number in the form of p q where p and q are coprimes and q 0 5 3 p q Add 3 to both sides 5 3 3 p q 3 5 p q 3 Subtract both sides p q 5 p q 3 5q p q 3
Learning Objectives After completing this section you should be able to Define and identify numbers that are irrational Simplify irrational numbers and express in lowest terms Add and subtract irrational numbers Multiply and divide irrational numbers Rationalize fractions with irrational denominators Therefore 4b 3 2k 3 8k 3 which gives b 3 2k 3 Since clearly 2k 3 is even b 3 is even which then implies b is even again since the cube of an odd number is odd So a and b are even contradicting the irreducibility of a b

show that 5 minus 2 root 3 is an irrational number - sqrt 5 is an irrational number Now let us assume 3 2 sqrt 5 be a rational number r So 3 2 sqrt 5 r 3 r 2 sqrt 5 3 r 2 sqrt 5 We know that r is rational 3 r 2 is rational so sqrt 5 is also rational This contradicts the statement that 5 is
