Answer 1

$\huge\bold{\mathtt{\purple{ A{\pink{ N{\green{ S{\blue{ W{\red{ E{\orange{ R}}}}}}}}}}}}}$

Part (i)

2 is a rational number.

This is True(T).

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).

2

+

5

=

5

, this is False(F).

Therefore,

T∪F=T (Truth value is tautology).
