Question 1/3 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8

यदि किसी संख्या का अभाज्य गुणनखंडन \(2\times3^3\times5^2\) है, तो वह संख्या कौन सी है?

If the prime factorisation of a number is \(2\times3^3\times5^2\), which number is it?

Explanation opens after your attempt
Correct Answer

A. 1350

Step 1

Concept

Calculate \(3^3=27\) and \(5^2=25\).

Step 2

Why this answer is correct

\(2\times27\times25=1350\).

Step 3

Exam Tip

Simplifying the two powers first makes multiplication easy. चरण 1: \(3^3=27\) और \(5^2=25\) निकालें। चरण 2: \(2\times27\times25=1350\)। चरण 3: दो घातों को पहले सरल करने से गुणा आसान होता है।

Question 2/3 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8

यदि \(1350=2\times3^b\times5^2\), तो (b) का मान क्या है?

If \(1350=2\times3^b\times5^2\), what is the value of (b)?

Explanation opens after your attempt
Correct Answer

A. 3

Step 1

Concept

\(1350=27\times50\).

Step 2

Why this answer is correct

\(27=3^3\) and \(50=2\times5^2\), so \(1350=2\times3^3\times5^2\).

Step 3

Exam Tip

Comparing gives (b=3). चरण 1: \(1350=27\times50\) है। चरण 2: \(27=3^3\) और \(50=2\times5^2\), इसलिए \(1350=2\times3^3\times5^2\)। चरण 3: तुलना करने पर (b=3) है।

Question 3/3 Medium Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 8

संख्या 1350 का अभाज्य गुणनखंडन कौन सा है?

Which is the prime factorisation of 1350?

Explanation opens after your attempt
Correct Answer

A. \(2\times3^3\times5^2\)

Step 1

Concept

Write \(1350=27\times50\).

Step 2

Why this answer is correct

\(27=3^3\) and \(50=2\times5^2\), so \(1350=2\times3^3\times5^2\).

Step 3

Exam Tip

Do not leave 27 and 50 in the final form. चरण 1: \(1350=27\times50\) लिखें। चरण 2: \(27=3^3\) और \(50=2\times5^2\), इसलिए \(1350=2\times3^3\times5^2\)। चरण 3: 27 और 50 को अंतिम रूप में न छोड़ें।
