Question

prove that 3+root5 is an irrational number ​

Answer 1

Answer:

hey mate !!!

_____ ur ans is :-_____

let us assume that 3+ √5 is a rational no . so

3+√5 = p/ q

√5 = p/q -3

√5= p - 3q / q

but as we know that √5 is an irrational no. and p-3q/q is a rational so that is not possible ....

hence our assumption was wrong and it is an irrational no.
