Question

prove that 3√3 is not rational number

Answer 1

let 3root 3 be a rational no

3 root 3 = p/q ( where p and q are co prime)

3root3=(p/q) square

3 root 3 = p square / q square

which is not possible because p and q are co prime .

our supposition is wrong .

hence 3 root 3 is a irrational no.
