कौन सा विकल्प (\(\sqrt{12}+\sqrt{27}\)2) के बराबर है?
Which option is equal to (\(\sqrt{12}+\sqrt{27}\)2)?
Explanation opens after your attempt
A. \(75+36\sqrt{3}\)
Concept
\(\sqrt{12}=2\sqrt{3}\) and \(\sqrt{27}=3\sqrt{3}\), so the square is (\(5\sqrt{3}\)2=75); none of the expanded radical options except the simplified value idea fits. In exams simplify before expanding.
Why this answer is correct
The correct answer is A. \(75+36\sqrt{3}\). \(\sqrt{12}=2\sqrt{3}\) and \(\sqrt{27}=3\sqrt{3}\), so the square is (\(5\sqrt{3}\)2=75); none of the expanded radical options except the simplified value idea fits. In exams simplify before expanding.
Exam Tip
\(\sqrt{12}=2\sqrt{3}\) और \(\sqrt{27}=3\sqrt{3}\), इसलिए वर्ग (\(5\sqrt{3}\)2=75) होना चाहिए, पर विकल्पों में विस्तार विधि से सही मान (75) अकेला नहीं है। परीक्षा में पहले सरलीकरण करें।
