Question 31/34 Easy Mathematics Real Numbers Fundamental Theorem of Arithmetic Class 10 Level 5

संख्या 88 में कौन-कौन से अलग-अलग अभाज्य गुणनखंड आते हैं?

Which distinct prime factors appear in 88?

Explanation opens after your attempt
Correct Answer

A. 2 और 112 and 11

Step 1

Concept

Write \(88=8\times11\).

Step 2

Why this answer is correct

\(8=2^3\), so \(88=2^3\times11\).

Step 3

Exam Tip

The distinct prime factors are 2 and 11. चरण 1: \(88=8\times11\) लिखें। चरण 2: \(8=2^3\), इसलिए \(88=2^3\times11\)। चरण 3: अलग-अलग अभाज्य गुणनखंड 2 और 11 हैं।

Question 32/34 Easy Mathematics Real Numbers Fundamental Theorem of Arithmetic Class 10 Level 5

यदि \(168=2^3\times3\times7\), तो 168 में अलग-अलग अभाज्य गुणनखंड कितने हैं?

If \(168=2^3\times3\times7\), how many distinct prime factors does 168 have?

Explanation opens after your attempt
Correct Answer

B. 3

Step 1

Concept

Look at distinct prime factors, not their powers.

Step 2

Why this answer is correct

In \(168=2^3\times3\times7\), the distinct primes are 2, 3, and 7.

Step 3

Exam Tip

Even if a power is large, count that prime once in the distinct list. चरण 1: अलग-अलग अभाज्य गुणनखंड देखें, उनकी घात नहीं। चरण 2: \(168=2^3\times3\times7\) में अलग-अलग अभाज्य 2, 3 और 7 हैं। चरण 3: घात बड़ी होने पर भी उस अभाज्य को अलग सूची में एक बार गिनें।

Question 33/34 Easy Mathematics Real Numbers Fundamental Theorem of Arithmetic Class 10 Level 4

संख्या 150 में कौन-कौन से अलग-अलग अभाज्य गुणनखंड हैं?

What are the distinct prime factors of 150?

Explanation opens after your attempt
Correct Answer

A. 2, 3 और 52, 3 and 5

Step 1

Concept

Write \(150=15\times10\).

Step 2

Why this answer is correct

\(15=3\times5\) and \(10=2\times5\), so the distinct prime factors are 2, 3, and 5.

Step 3

Exam Tip

Write a repeated factor only once in a distinct list. चरण 1: \(150=15\times10\) लिखें। चरण 2: \(15=3\times5\) और \(10=2\times5\), इसलिए अलग-अलग अभाज्य गुणनखंड 2, 3 और 5 हैं। चरण 3: दोहराए गए गुणनखंड को अलग-अलग सूची में एक बार ही लिखें।

Question 34/34 Easy Mathematics Real Numbers Fundamental Theorem of Arithmetic Class 10 Level 4

यदि \(72=2^3\times3^2\), तो 72 में अलग-अलग अभाज्य गुणनखंड कितने हैं?

If \(72=2^3\times3^2\), how many distinct prime factors does 72 have?

Explanation opens after your attempt
Correct Answer

B. 2

Step 1

Concept

Look at distinct prime factors, not their powers.

Step 2

Why this answer is correct

In \(72=2^3\times3^2\), the distinct primes are 2 and 3.

Step 3

Exam Tip

The number of distinct prime factors and total prime factors are different. चरण 1: अलग-अलग अभाज्य गुणनखंडों को देखें, घातों को नहीं गिनें। चरण 2: \(72=2^3\times3^2\) में अलग-अलग अभाज्य 2 और 3 हैं। चरण 3: अलग-अलग गुणनखंडों की संख्या और कुल गुणनखंडों की संख्या अलग होती है।
