Answer: The answer is 5 + √9.
Step-by-step explanation: 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.
