If a number has prime factorisation (2^6\times3^4\times5^3\times7), how many prime factors are there if repetition is counted?
Answer and explanation
Correct answer: 14
Step 1: To count with repetition, add the exponents. Step 2: (2^6) gives 6, (3^4) gives 4, (5^3) gives 3, and 7 gives 1 factor. Step 3: Total (6+4+3+1=14), so the answer is 14.
