The correct answer is 15.
If p and q are prime numbers, then for p\(^m\)q\(^n\), the number of divisors is (m+1)(n+1).
Thus the number of divisors for N\(^2\) × P\(^4\) is (2+1)(4+1) = 15
Another way to solve this problem is by providing numbers for N and P. Let’s put 2 for N and 3 for P. Then, the value of N\(^2\) × P\(^4\) is 2\(^2\) × 3\(^4\) = 324
Now, find the factors of 324.
324: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
324 have 15 factors.
