give me answer of 5 th question​

Answer 1

Expect 2&6 one all numbers are irrational.

Answer 2

Answer:

Step-by-step explanation:

√7 is not a perfect square root, so it is an irrational number.

We have, ∴√4 can be expressed in the form of , p/ q, so it is a rational number.

The decimal representation of √4 is 2.0. 2 is a rational number, whereas √3 is an irrational number.

Because, sum of a rational number and an irrational number is an irrational number, so 2 +√3 is an irrational number.

√ 2 is an irrational number. Also √3 is an irrational number.

The sum of two irrational numbers is irrational. √ 3+√ 2 is an irrational number. √ 5 is an irrational number.

Also √3 is an irrational number.

The sum of two irrational numbers is irrational.

√ 3 +√5 is an irrational number.

We have, Now, 6 is a rational number, whereas 4√2 is an irrational number.

The difference of a rational number and an irrational number is an irrational number. So, 6- 4√2 is an irrational number.

(√2 - 2 ) 2 is an irrational number.

We have, Since 2 is a rational number.

(2 -√2 )(2 +√2) is a rational number.
