Question

$\sqrt{2}$
is irrational number​

Answer 1

Answer:

yes 2is a rational number

Answer 2

Answer:

Part (i)

2 is a rational number.

This is True(T).

$\sqrt{2}$

is an irrational number.

This is True(T).

Therefore,

T∩T=T (Truth value is tautology).

Part (ii)

2+3=5, this is True(T).

$\sqrt{2} + \sqrt{5} = \sqrt{5}$

, this is False(F).

Therefore,

T∪F=T (Truth value is tautology).
