step by step​

Answer 1

Answer:

1. (i) is rational
2. (ii) is irrational

Step-by-step explanation:

1. $\sqrt{169} = \sqrt{13 \times 13} = 13$13, which is rational.

2. But 3.418126..... is irrational as it is non-terminating and non-repeating.

Answer 2

Step-by-step explanation:

i)$\sqrt{169}$ = $\sqrt{13 * 13}$ = 13

13 is a rational no. since it is a natural no. (all natural no.s are rational no.s) which makes $\sqrt{169}$ rational

ii) 3.418126..... is irrational since it is non terminating and non recurring (irrational no.s are always non terminating and non recurring )
