## Task

Let's say we have a positive integer, `$n$`. You have to find the smallest possible positive integer that when multiplied by `$n$`, becomes a perfect power of integer `$k$`. A perfect power of `$k$` is any positive integer that can be represented as `$a^k$`. For example if `$k = 2$`, then `$36$` is a perfect power of `$k$`, but `$27$` isn't.

## Examples

```python
n, k = 100, 3  return  10, #because 10*100 becomes 1000, and 1000 = 10**3
n, k = 36, 2   return   1, #because 36 is already a perfect square 6**2
n, k = 72, 4   return  18, #because 18*72 = 1296 = 6**4
```

**Notes:** 
+ `$k, n \in \mathbb{N} $` and `$ 1 \lt n \lt 10^6,\text{ } 1 \lt k \lt 10 $`
+ However, the output may be way larger than `$10^6$`.
