Assassin reason Association 2 plus square root 3 rational number reason the sum of a rational number ending rational number is always irrational

Answer: Both Assertion (A) and Reason (R) are true, and Reason (R) is the correct explanation of Assertion (A).

Step-by-step solution

Step 1: Evaluate the Reason (R)

We test whether Reason (R) is mathematically true. The difference of two rational numbers is always rational, so if the sum of a rational number and an irrational number were rational, the irrational number would have to be rational, which is impossible. Thus, the sum of a rational number and an irrational number is always irrational, making Reason (R) true.

Step 2: Evaluate the Assertion (A)

Here, 22 is an integer and therefore a rational number, while 3\sqrt{3} is a well-known irrational number. Adding the rational number 22 to the irrational number 3\sqrt{3} yields 2+32 + \sqrt{3}, which is irrational. Therefore, Assertion (A) is true.

Step 3: Determine the Relationship Between A and R

Assertion (A) claims that 2+32 + \sqrt{3} is irrational precisely because it is the sum of a rational number (22) and an irrational number (3\sqrt{3}). Reason (R) states this exact general property. Hence, Reason (R) correctly explains Assertion (A).
