Please solve the programming task below using a self-contained code snippet in a markdown code block.

Given two arrays of integers nums1 and nums2, return the number of triplets formed (type 1 and type 2) under the following rules:

Type 1: Triplet (i, j, k) if nums1[i]2 == nums2[j] * nums2[k] where 0 <= i < nums1.length and 0 <= j < k < nums2.length.
Type 2: Triplet (i, j, k) if nums2[i]2 == nums1[j] * nums1[k] where 0 <= i < nums2.length and 0 <= j < k < nums1.length.

 
Please complete the following python code precisely:
```python
class Solution:
    def numTriplets(self, nums1: List[int], nums2: List[int]) -> int:
```
