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

\(\sqrt{384}+\sqrt{54}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{384}+\sqrt{54}\)?

Explanation opens after your attempt
Correct Answer

A. \(11\sqrt{6}\)

Step 1

Concept

\(\sqrt{384}=8\sqrt{6}\) and \(\sqrt{54}=3\sqrt{6}\).

Step 2

Why this answer is correct

\(8\sqrt{6}+3\sqrt{6}=11\sqrt{6}\).

Step 3

Exam Tip

Add radicals only after they become like radicals. चरण 1: \(\sqrt{384}=8\sqrt{6}\) और \(\sqrt{54}=3\sqrt{6}\)। चरण 2: \(8\sqrt{6}+3\sqrt{6}=11\sqrt{6}\)। चरण 3: समान वर्गमूल बनने के बाद ही उन्हें जोड़ें।

\(\sqrt{216}+\sqrt{54}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{216}+\sqrt{54}\)?

Explanation opens after your attempt
Correct Answer

A. \(9\sqrt{6}\)

Step 1

Concept

\(\sqrt{216}=6\sqrt{6}\) and \(\sqrt{54}=3\sqrt{6}\).

Step 2

Why this answer is correct

\(6\sqrt{6}+3\sqrt{6}=9\sqrt{6}\).

Step 3

Exam Tip

Add radicals only after they become like radicals. चरण 1: \(\sqrt{216}=6\sqrt{6}\) और \(\sqrt{54}=3\sqrt{6}\)। चरण 2: \(6\sqrt{6}+3\sqrt{6}=9\sqrt{6}\)। चरण 3: समान वर्गमूल बनने के बाद ही उन्हें जोड़ें।

\(\sqrt{150}+\sqrt{24}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{150}+\sqrt{24}\)?

Explanation opens after your attempt
Correct Answer

A. \(7\sqrt{6}\)

Step 1

Concept

\(\sqrt{150}=5\sqrt{6}\) and \(\sqrt{24}=2\sqrt{6}\).

Step 2

Why this answer is correct

\(5\sqrt{6}+2\sqrt{6}=7\sqrt{6}\).

Step 3

Exam Tip

Add radicals only after they become like radicals. चरण 1: \(\sqrt{150}=5\sqrt{6}\) और \(\sqrt{24}=2\sqrt{6}\)। चरण 2: \(5\sqrt{6}+2\sqrt{6}=7\sqrt{6}\)। चरण 3: समान वर्गमूल बनने के बाद ही जोड़ें।

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

कौन-सी संख्या (8) और (9) के बीच स्थित अपरिमेय संख्या है?

Which number is an irrational number between (8) and (9)?

Explanation opens after your attempt
Correct Answer

A. \(\sqrt{65}\)

Step 1

Concept

Since (64<65<81), \(8<\sqrt{65}<9\).

Step 2

Why this answer is correct

(65) is not a perfect square, so \(\sqrt{65}\) is irrational.

Step 3

Exam Tip

The square root of a number between two perfect squares lies between their roots. चरण 1: (64<65<81), इसलिए \(8<\sqrt{65}<9\)। चरण 2: (65) पूर्ण वर्ग नहीं है, इसलिए \(\sqrt{65}\) अपरिमेय है। चरण 3: दो पूर्ण वर्गों के बीच की संख्या का वर्गमूल उनके मूलों के बीच होता है।

\(\sqrt{2}\times\sqrt{32}\) का मान क्या है?

What is the value of \(\sqrt{2}\times\sqrt{32}\)?

Explanation opens after your attempt
Correct Answer

A. (8)

Step 1

Concept

\(\sqrt{2}\times\sqrt{32}=\sqrt{64}\).

Step 2

Why this answer is correct

\(\sqrt{64}=8\), so the result is rational.

Step 3

Exam Tip

In multiplication, multiply the numbers inside the square roots. चरण 1: \(\sqrt{2}\times\sqrt{32}=\sqrt{64}\)। चरण 2: \(\sqrt{64}=8\), इसलिए परिणाम परिमेय है। चरण 3: गुणन में वर्गमूलों के अंदर की संख्याएँ गुणा करें।

\(\sqrt{6}\) का दशमलव विस्तार कैसा होगा?

What kind of decimal expansion does \(\sqrt{6}\) have?

Explanation opens after your attempt
Correct Answer

C. अनवसानी और अनावर्तीNon-terminating and non-recurring

Step 1

Concept

(6) is not a perfect square.

Step 2

Why this answer is correct

So \(\sqrt{6}\) is irrational and its decimal is non-terminating and non-recurring.

Step 3

Exam Tip

An irrational number has no fixed repeating pattern. चरण 1: (6) पूर्ण वर्ग नहीं है। चरण 2: इसलिए \(\sqrt{6}\) अपरिमेय है और इसका दशमलव अनवसानी अनावर्ती होगा। चरण 3: अपरिमेय संख्या में स्थिर दोहराव नहीं होता।

Question Easy Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 14

\(\sqrt{63}\) को सरल कीजिए।

Simplify \(\sqrt{63}\).

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{7}\)

Step 1

Concept

\(63=9 \times 7\).

Step 2

Why this answer is correct

\(\sqrt{63}=\sqrt{9 \times 7}=3\sqrt{7}\).

Step 3

Exam Tip

Remember to take a perfect square like (9) outside the root. चरण 1: \(63=9 \times 7\) है। चरण 2: \(\sqrt{63}=\sqrt{9 \times 7}=3\sqrt{7}\)। चरण 3: (9) जैसे पूर्ण वर्ग को बाहर निकालना याद रखें।
