Question

Prove that 3 under root 2/5 is an irrational number

Answer 1

let us assume that 3 root 2 by 5is a rational number

P by Q is equals to 3 under root 2 by 5

then it will be like 3 under root 2 by 5 q is equals to p

squaring on both sides

it becomes 3root2 by 5 square into Q square is equal to p²

then we have to consider that 3 under root 2 by 5 p²
then it also divides p

the three under root 2 by 5 is irrational number and please call is a rational number so this is a contradiction method Hansa resumption was wrong and 3 under root 2 by 5 is a rational number
