If \(N=2^2 \times 7^2\), what is the value of (N)?

Explanation opens after your attempt
Correct Answer

C. 196

Step 1

Concept

\(2^2=4\) and \(7^2=49\).

Step 2

Why this answer is correct

\(4 \times 49=196\), so (N=196).

Step 3

Exam Tip

Knowing squares helps solve such calculations quickly. चरण 1: \(2^2=4\) और \(7^2=49\) है। चरण 2: \(4 \times 49=196\), इसलिए (N=196)। चरण 3: वर्गों की जानकारी रखने से ऐसी गणना जल्दी होती है।

Correct Answer

C. 104

Step 1

Concept

\(2^3=8\).

Step 2

Why this answer is correct

\(8 \times 13=104\), so (n=104).

Step 3

Exam Tip

First evaluate the small power, then multiply. चरण 1: \(2^3\) का मान (8) है। चरण 2: \(8 \times 13=104\), इसलिए (n=104)। चरण 3: पहले छोटी घात निकालकर फिर गुणा करें।

Question 3/12 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 12

\(2^3 \times 3 \times 7\) का मान क्या है?

What is the value of \(2^3 \times 3 \times 7\)?

Explanation opens after your attempt
Correct Answer

C. 168

Step 1

Concept

First evaluate \(2^3\).

Step 2

Why this answer is correct

C. 225

Step 1

Concept

\(3^2=9\) and \(5^2=25\).

Step 2

Why this answer is correct

\(9 \times 25=225\), so (N=225).

Step 3

Exam Tip

Remembering squares makes such calculations faster. चरण 1: \(3^2=9\) और \(5^2=25\) है। चरण 2: \(9 \times 25=225\), इसलिए (N=225)। चरण 3: वर्गों को याद रखने से ऐसी गणना तेज होती है।

D. 132

Step 1

Concept

\(2^2=4\).

Step 2

Why this answer is correct

\(4 \times 3 \times 11=12 \times 11=132\).

Step 3

Exam Tip

Forming small products first reduces mistakes. चरण 1: \(2^2\) का मान (4) है। चरण 2: \(4 \times 3 \times 11=12 \times 11=132\)। चरण 3: छोटे गुणनफल बनाकर आगे गुणा करने से गलती कम होती है।

Question 6/12 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 11

\(2^2 \times 3^3 \times 5\) का मान क्या है?

What is the value of \(2^2 \times 3^3 \times 5\)?

Explanation opens after your attempt
Correct Answer

B. 540

Step 1

Concept

Evaluate the powers first.

Step 2

Why this answer is correct

\(2^2=4\) and \(3^3=27\), so \(4 \times 27 \times 5=540\).

Step 3

Exam Tip

Solving powers before multiplication is a safe method. चरण 1: पहले घातों का मान निकालें। चरण 2: \(2^2=4\) और \(3^3=27\), इसलिए \(4 \times 27 \times 5=540\)। चरण 3: गणना में पहले घात और फिर गुणा करना सुरक्षित तरीका है।

Question 7/12 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 10

किस संख्या का अभाज्य गुणनखंडन \(3^3 \times 7\) है?

Which number has prime factorisation \(3^3 \times 7\)?

Explanation opens after your attempt
Correct Answer

B. 189

Step 1

Concept

\(3^3=27\).

Step 2

Why this answer is correct

\(27 \times 7=189\), so the number is (189).

Step 3

Exam Tip

Remembering small powers helps you calculate faster. चरण 1: \(3^3=27\) है। चरण 2: \(27 \times 7=189\), इसलिए संख्या (189) है। चरण 3: पहले छोटी घातों को याद करके गणना तेज करें।

C. 45

Step 1

Concept

\(3^2=9\).

Step 2

Why this answer is correct

\(9 \times 5=45\), so (m=45).

Step 3

Exam Tip

Keeping the order of powers and multiplication clear reduces mistakes. चरण 1: \(3^2\) का मान (9) है। चरण 2: \(9 \times 5=45\), इसलिए (m=45)। चरण 3: घात और गुणा का क्रम ठीक रखने से गलती कम होती है।
