(ii) 7√5

Let us assume that 7√5 is a rational number.

Then, 7√5 = a/b, where a and b have no common factors other than 1.

(7√5) b = a

√5 = a/7b

Since, a, 7, and b are integers, so, a/7b is a rational number. This means √5 is rational. But this contradicts the fact that √5 is irrational.

So, our assumption was wrong. Therefore, 7√5 is an irrational number.

(iii) 6 + √2

Let us assume that 6 + √2 is rational.

Then, 6 + √2 = a/b, where a and b have no common factors other than 1.

√2 = (a/b) - 6

Since, a, b, and 6 are integers, so, a/b - 6 is a rational number. This means √2 is also a rational number.

But this contradicts the fact that √2 is irrational. So, our assumption was wrong.

Therefore, 6 + √2 is an irrational number.
