Question 1/8 Medium Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 15

\(\sqrt{507}-\sqrt{192}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{507}-\sqrt{192}\)?

Explanation opens after your attempt
Correct Answer

A. \(5\sqrt{3}\)

Step 1

Concept

\(\sqrt{507}=13\sqrt{3}\) and \(\sqrt{192}=8\sqrt{3}\).

Step 2

Why this answer is correct

\(13\sqrt{3}-8\sqrt{3}=5\sqrt{3}\).

Step 3

Exam Tip

Simplify radicals completely before subtracting. चरण 1: \(\sqrt{507}=13\sqrt{3}\) और \(\sqrt{192}=8\sqrt{3}\)। चरण 2: \(13\sqrt{3}-8\sqrt{3}=5\sqrt{3}\)। चरण 3: घटाने से पहले वर्गमूलों को पूरी तरह सरल करें।

Question 2/8 Medium Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 15

\(\sqrt{147}-\sqrt{75}\) 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।

Step 1

Concept

\(\sqrt{363}=11\sqrt{3}\) and \(\sqrt{75}=5\sqrt{3}\).

Step 2

Why this answer is correct

\(11\sqrt{3}-5\sqrt{3}=6\sqrt{3}\).

Step 3

Exam Tip

Simplify radicals completely before subtracting. चरण 1: \(\sqrt{363}=11\sqrt{3}\) और \(\sqrt{75}=5\sqrt{3}\)। चरण 2: \(11\sqrt{3}-5\sqrt{3}=6\sqrt{3}\)। चरण 3: घटाने से पहले वर्गमूलों को पूरी तरह सरल करें।

\(\sqrt{98}-\sqrt{32}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{98}-\sqrt{32}\)?

Explanation opens after your attempt
Correct Answer

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

Step 1

Concept

\(\sqrt{98}=7\sqrt{2}\) and \(\sqrt{32}=4\sqrt{2}\).

Step 2

Why this answer is correct

\(7\sqrt{2}-4\sqrt{2}=3\sqrt{2}\).

Step 3

Exam Tip

Convert radicals into like radicals before subtracting. चरण 1: \(\sqrt{98}=7\sqrt{2}\) और \(\sqrt{32}=4\sqrt{2}\)। चरण 2: \(7\sqrt{2}-4\sqrt{2}=3\sqrt{2}\)। चरण 3: वर्गमूलों को घटाने से पहले समान वर्गमूल में बदलें।

Question 5/8 Medium Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 13

\(\sqrt{200}-\sqrt{72}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{200}-\sqrt{72}\)?

Explanation opens after your attempt
Correct Answer

A. \(4\sqrt{2}\)

Step 1

Concept

\(\sqrt{200}=10\sqrt{2}\) and \(\sqrt{72}=6\sqrt{2}\).

Step 2

Why this answer is correct

\(10\sqrt{2}-6\sqrt{2}=4\sqrt{2}\).

Step 3

Exam Tip

Before subtracting radicals, write both terms in simplified form. चरण 1: \(\sqrt{200}=10\sqrt{2}\) और \(\sqrt{72}=6\sqrt{2}\)। चरण 2: \(10\sqrt{2}-6\sqrt{2}=4\sqrt{2}\)। चरण 3: वर्गमूल घटाने में पहले दोनों पदों को सरल रूप में लिखें।
