\(\sqrt{147}-\sqrt{75}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{147}-\sqrt{75}\)?

Explanation opens after your attempt
Correct Answer

A. \(2\sqrt{3}\)

Step 1

Concept

\(\sqrt{147}=7\sqrt{3}\) and \(\sqrt{75}=5\sqrt{3}\).

Step 2

Why this answer is correct

\(7\sqrt{3}-5\sqrt{3}=2\sqrt{3}\).

Step 3

Exam Tip

Before subtracting radicals, convert them into like radicals. चरण 1: \(\sqrt{147}=7\sqrt{3}\) और \(\sqrt{75}=5\sqrt{3}\)। चरण 2: \(7\sqrt{3}-5\sqrt{3}=2\sqrt{3}\)। चरण 3: वर्गमूलों को घटाने से पहले समान वर्गमूल में बदलना जरूरी है।
