How many positive integers is the 17th power of n = 12 multiplied by the 12th power of 5

The original title is:
N=12^17*5^12=?
The process of calculation (with a computer calculator)
12^17=2,218,611,106,740,436,992
5^12=244,140,625
So: n = 12 ^ 17 * 5 ^ 12
=541,653,102,231,552*10^12
Results: the number word has 15 digits, 0 has 12 digits

If the 7th power of a number is negative, what is its 17th power
Answer me quickly

It's a negative number

Let n be a positive integer and 1 * 2 * 3 *... * n + 3 be a complete square number

When n ≥ 5, 1 × 2 × The single digit of x n + 3 is 3, which can not be a complete square;
When n < 5, it is obvious that n = 1,3 satisfies the condition, so the value of n is 1 or 3
