Step 1
Concept
To count with repetition, add the exponents.
Step 2
Why this answer is correct
\(2^2\) gives 2, \(3^3\) gives 3, and (5) gives 1 factor.
Step 3
Exam Tip
Total (2+3+1=6), so the answer is 6. चरण 1: दोहराव सहित कुल संख्या के लिए घातों को जोड़ें। चरण 2: \(2^2\) से 2, \(3^3\) से 3 और (5) से 1 गुणनखंड मिलते हैं। चरण 3: कुल (2+3+1=6), इसलिए उत्तर 6 है।
