\( \sqrt{a+b}=\sqrt{a}+\sqrt{b} \) को जाँचने के लिए कौन सा उदाहरण इसे गलत दिखाता है?
Which example shows that \( \sqrt{a+b}=\sqrt{a}+\sqrt{b} \) is false?
Explanation opens after your attempt
A. \( \sqrt{4+9}\neq\sqrt{4}+\sqrt{9} \)
Concept
\( \sqrt{13} \) and (2+3=5) are not equal. Therefore square root cannot be distributed directly over addition.
Why this answer is correct
The correct answer is A. \( \sqrt{4+9}\neq\sqrt{4}+\sqrt{9} \). \( \sqrt{13} \) and (2+3=5) are not equal. Therefore square root cannot be distributed directly over addition.
Exam Tip
\( \sqrt{13} \) और (2+3=5) बराबर नहीं हैं। इसलिए वर्गमूल को जोड़ के अंदर सीधे नहीं बाँटते।
