Answer:
6+√2 is irrational.
Step-by-step explanation:
Let us assume that 6+√2 is rational.
That is , we can find coprimes a and b (b≠0) such that
6+\sqrt{2}=\frac{a}{b}6+
2
=
b
a
\implies \sqrt{2}=\frac{a}{b}-6⟹
2
=
b
a
−6
\implies \sqrt{2}=\frac{a-6b}{b}⟹
2
=
b
a−6b
Since , a and b are integers , \frac{a-6b}{b}
b
a−6b
is rational ,and so √2 is rational.
But this contradicts the fact that √2 is irrational.
So, we conclude that 6+√2 is irrational.
