What is the prime factorisation of (196)?
Explanation opens after your attempt
Correct Answer
A. \(2^2 \times 7^2\)
Concept
Write (196) as \(14 \times 14\).
Why this answer is correct
Since \(14=2 \times 7\), \(196=2^2 \times 7^2\).
Exam Tip
Do not leave composite bases like (4) or (14) in the final answer. चरण 1: (196) को \(14 \times 14\) लिखें। चरण 2: \(14=2 \times 7\), इसलिए \(196=2^2 \times 7^2\)। चरण 3: अंतिम उत्तर में (4) या (14) जैसे संयुक्त आधार न छोड़ें।
