यदि \(P=\sqrt{363}-\sqrt{147}+\sqrt{75}\) है, तो (P) किसके बराबर है?
If \(P=\sqrt{363}-\sqrt{147}+\sqrt{75}\), what is (P) equal to?
Explanation opens after your attempt
B. \(9\sqrt{3}\)
Concept
\(\sqrt{363}=11\sqrt{3}\), \(\sqrt{147}=7\sqrt{3}\), and \(\sqrt{75}=5\sqrt{3}\). Therefore \(P=9\sqrt{3}\).
Why this answer is correct
The correct answer is B. \(9\sqrt{3}\). \(\sqrt{363}=11\sqrt{3}\), \(\sqrt{147}=7\sqrt{3}\), and \(\sqrt{75}=5\sqrt{3}\). Therefore \(P=9\sqrt{3}\).
Exam Tip
\(\sqrt{363}=11\sqrt{3}\), \(\sqrt{147}=7\sqrt{3}\) और \(\sqrt{75}=5\sqrt{3}\) है। इसलिए \(P=9\sqrt{3}\) है।
