Answer 1

Answer:

only four not two three and five

Answer 2

▬▬▬▬▬▬▬▬▬▬▬▬▬▬

→ Rational number are those number which are expressible in form of p/q, where p and q are integers and q≠0.

→ If √n is rational number then the value of n will be 4 because 4 is a perfect square it comes out of radical and becomes 2.

→ Now, 2 can be expressed as 2/1 which is in the form of p/q where p and q are integers and also q≠0.

∴ The correct answer is 4.
