Question

prove that 2/√3 is irrational.

Answer 1

let 2 by root 3 be rational no.

2 by root 3 ×3 will also be a rational no.
root 3 is rational no.


this contradicts the fact that root 3 is an irrational no.
hence, our assumption is wrong
therefore, 2 by root 3 is an irrational no.

Answer 2

hey!

here is the answer

2/√3 is an irrational number ⏬⏬⏬⏬⏬✴❕❕❕❕❕❗❗❣❣

let's do it

let 2/√3 a rational number

then 2/√3= a/b where a and b are integers and b is not equal to 0 ..

then 2/√3 =a/b ( here we will do cross multiplication )

and we get

√3a/2b and it is an irrational number , so the contradiction we have supposed is wrong ..

hence, 2/√3 is an irrational number

hope it helps
