Correct Answer

A. यह \(3\sqrt{3}\) है और अपरिमेय हैIt is \(3\sqrt{3}\) and irrational

Step 1

Concept

Add the coefficients of like surds.

Step 2

Why this answer is correct

\(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\), and \(\sqrt{3}\) is irrational.

Step 3

Exam Tip

Coefficients add; the number inside the radical remains unchanged. चरण 1: समान मूल वाले पदों के गुणांक जोड़े जाते हैं। चरण 2: \(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\), और \(\sqrt{3}\) अपरिमेय है। चरण 3: गुणांक जुड़ते हैं, मूल के अंदर की संख्या नहीं बदलती।
