Answer 1

Answer:

1)Between any 2 rational numbers there exist infinitely many irrational number.

0.2010010001...,0.2020020002....are two such irrational numbers.

2)√2=1.414 and √5 = 2.236...

Therefore, a rational number between √2 and √5 are 1.412,1.413,1.414.

3)1)√7=irrational number

2)√4=2=rational number

3)(√2-2)^2=(√2)^2-2^2

=2-4=-2=irrational number.

4)(√2+√3)^2

=(√2)^2+(√3)^2

=2+3=5=rational number.

5)(2-√2)(2+√2)

=2^2-(√2)^2

=4-2

=2=rational number
