Answer 1

Answer:

1. Irrational
2. Irrational

(Operations of rational and irrational result in irrational as listed below)

Explanation:

Here mate let me tell you something so you can remember what to do!!

IR _ Irrational , R_ Rational then

• IR + R = IR
• IR - R or R - IR = IR
• IR x R = IR
• IR ÷ R or R ÷ IR = IR
• Operations with both (between) irrational numbers or only between rational numbers themselves cannot be fixed...it may change...

Also about rational numbers..

• Either terminating or must be repeating decimal
• Can be written in p/q form or fractional form.
