यदि \(m=2^3\times3^2\times7\times11\), तो (m) में अलग-अलग अभाज्य गुणनखंड कितने हैं?
If \(m=2^3\times3^2\times7\times11\), how many distinct prime factors does (m) have?
Explanation opens after your attempt
Correct Answer
C. 4
Concept
Look at distinct prime factors, not powers.
Why this answer is correct
In (m), the distinct primes are 2, 3, 7, and 11.
Exam Tip
Count 2 and 3 only once each despite their powers. चरण 1: अलग-अलग अभाज्य गुणनखंड देखें, घातें नहीं। चरण 2: (m) में 2, 3, 7 और 11 चार अलग-अलग अभाज्य गुणनखंड हैं। चरण 3: \(2^3\) और \(3^2\) में 2 और 3 को एक-एक बार गिनें।
