Answer 1

Answer:2- root 3 is an irrational no.

Step-by-step explanation:

Solution:- let us consider that 2 - root 3 is a rational no.

According to definitions

p/q = 2 - root 3 ( p and q are integers where q not equals to 0, p and are co prime no.)

p/q - 2 = - root 3

Rational no. = Irrational no.

This can't be possible.

Therefore,

Our assumption was wrong that 2 - root 3 is a rational no.

Hence, 2 - root 3 is an Irrational no.
