Question

6+root 2 is irrational number​

Answer 1

Answer:

Let us assume that 6+√2 is a rational number.

Then,

(6+√2)-6) = √2 ,is also a rational number       (difference of rationals is a rational number)

But this contradicts the fact that √2 is an irrational number.

This contradiction arises  by assuming that 6+√2 is a rational number.

Thus,our assumption was wrong, 6+√2 is an irrational number

Hence proved..
