Correct Answer

A. 415800

Step 1

Concept

Calculate \(2^3=8\), \(3^3=27\), and \(5^2=25\).

Step 2

Why this answer is correct

\(8\times27\times25\times7\times11=415800\).

Step 3

Exam Tip

When there are many factors, multiply in small groups. चरण 1: \(2^3=8\), \(3^3=27\) और \(5^2=25\) निकालें। चरण 2: \(8\times27\times25\times7\times11=415800\)। चरण 3: कई गुणनखंड हों तो छोटे समूह बनाकर गुणा करें।

संख्या 415800 का सही अभाज्य गुणनखंडन क्या है?

What is the correct prime factorisation of 415800?

Explanation opens after your attempt
Correct Answer

A. \(2^3\times3^3\times5^2\times7\times11\)

Step 1

Concept

Write \(415800=8\times51975\).

Step 2

Why this answer is correct

\(51975=3^3\times5^2\times7\times11\), so \(415800=2^3\times3^3\times5^2\times7\times11\).

Step 3

Exam Tip

Do not leave 51975 in the final form. चरण 1: \(415800=8\times51975\) लिखें। चरण 2: \(51975=3^3\times5^2\times7\times11\), इसलिए \(415800=2^3\times3^3\times5^2\times7\times11\)। चरण 3: 51975 को अंतिम रूप में न छोड़ें।
