Hard Mathematics Chapter 1: Real Numbers Class 10 Level 14

यदि \(x=\sqrt{11}+\sqrt{44}\), तो (x) का सरल रूप और प्रकृति क्या है?

If \(x=\sqrt{11}+\sqrt{44}\), what is the simplified form and nature of (x)?

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{11}\), अपरिमेय\(3\sqrt{11}\), irrational

Step 1

Concept

\(\sqrt{44}=\sqrt{4\times11}=2\sqrt{11}\).

Step 2

Why this answer is correct

Hence \(x=\sqrt{11}+2\sqrt{11}=3\sqrt{11}\), and \(\sqrt{11}\) is irrational.

Step 3

Exam Tip

For like surds, add only the coefficients, not the numbers inside the roots. चरण 1: \(\sqrt{44}=\sqrt{4\times11}=2\sqrt{11}\) होता है। चरण 2: इसलिए \(x=\sqrt{11}+2\sqrt{11}=3\sqrt{11}\), और \(\sqrt{11}\) अपरिमेय है। चरण 3: समान मूल वाले पदों में केवल गुणांक जोड़ें, मूल के अंदर की संख्या नहीं।
