We have the number ```12385```. We want to know the value of the closest cube but higher than 12385. The answer will be ```13824```.
Now, another case. We have the number ```1245678```. We want to know the 5th power, closest and higher than that number. The value will be ```1419857```.
We need a function ```find_next_power``` ( ```findNextPower``` in JavaScript, CoffeeScript and Haskell), that receives two arguments, a value ```val```, and the exponent of the power,``` pow_```, and outputs the value that we want to find.
Let'see some cases:
```python
find_next_power(12385, 3) == 13824
find_next_power(1245678, 5) == 1419857
```
The value, ```val``` will be always a positive integer.
The power, ```pow_```, always higher than ```1```.
Happy coding!!
