Question

prove that 3-root 7 square is irrational???

Answer 1

Step-by-step explanation:

let 3- root7 is rational

3- root 7 = p / q

- root 7 = p/q - 3

- root 7 = 3p - q / q

irrational = rational

this situation is not possible

so, our assumption is wrong

hence we can say that 3 - root7 is irrational
