कौन-सा विकल्प \(2\sqrt{15}\) के बराबर है?

Which option is equal to \(2\sqrt{15}\)?

Explanation opens after your attempt
Correct Answer

B. \(\sqrt{60}\)

Step 1

Concept

\(2\sqrt{15}=\sqrt{4}\sqrt{15}\).

Step 2

Why this answer is correct

Therefore \(2\sqrt{15}=\sqrt{60}\).

Step 3

Exam Tip

When moving a coefficient inside a square root, its square goes inside. चरण 1: \(2\sqrt{15}=\sqrt{4}\sqrt{15}\) लिखा जा सकता है। चरण 2: इसलिए \(2\sqrt{15}=\sqrt{60}\)। चरण 3: गुणांक को मूल के अंदर ले जाते समय उसका वर्ग अंदर जाता है।
