Answer 2

Answer:

We are given to identify the rational number from the given four numbers.

The first number is 5 - √3.

Since √3 = 1.732..., which is irrational, so 5 - √3 is also irrational.

The first number is 5 + √3.

Since √3 is irrational, so 5 + √3 is also irrational.

The third number is 4 + √2.

Since √2 = 1.414..., which is irrational, so 4 + √2 is also irrational.

The fourth number is 5 + √9.

Since √9 = 3, which is rational, so 5 + √9 is also rational.

Thus, the correct option is 5 + √9.
