Proove that root5 is irrrational |
|
Answer» Let us assume that √5 is a rational number.we know that the rational numbers are in the form of p/q form where p,q are intezers.so, √5 = p/q p = √5qWe know that \'p\' is a rational number. so √5 q must be rational since it equals to pbut it doesnt occurs with √5 since its not an intezerTherefore, p =\xa0√5qthis contradicts the fact that √5 is an irrational number.Hence our assumption is wrong and √5 is an irrational number. ye kesa answer h 10 |
