Prove 2+√5 is irTional |
| Answer» We preassume that\xa0{tex}2 + \\sqrt 5 {/tex}\xa0is a rational number.So it can be written as\xa0{tex}\\frac{a}{b}{/tex}, where a, b are co-prime integers and b is not zero.The new equation will be as below:\xa0{tex}\\implies 2 + \\sqrt 5 = \\frac{a}{b}{/tex}So, we will get\xa0{tex}\\sqrt 5 = \\frac{a}{b} - 2{/tex}As we know that 2 and {tex}\\frac{a}{b}{/tex}\xa0are rational numbers, their difference will be rational number only.on the other hand,\xa0{tex}\\sqrt 5 {/tex}\xa0is an irrational number and it can not be written as\xa0{tex}\\frac{a}{b}{/tex}.So, this contradicts the fact that\xa0{tex}\\sqrt 5 {/tex} is a rational number.\xa0Therefore our assumption is wrong and {tex}2 + \\sqrt 5 {/tex}\xa0is irrational. | |

How to prove root 5 is irrational number |
| Answer» let root 5 be rational then it must in the form of p/q [q is not equal to 0][p and q are co-prime] root 5=p/q => root 5 * q = p squaring on both sides => 5*q*q = p*p ------> 1 p*p is divisible by 5 p is divisible by 5 p = 5c [c is a positive integer] [squaring on both sides ] p*p = 25c*c --------- > 2 sub p*p in 1 5*q*q = 25*c*c q*q = 5*c*c => q is divisble by 5 thus q and p have a common factor 5 there is a contradiction as our assumsion p &q are co prime but it has a common factor so √5 is an irrational | |
