Hello,

I have an integral which I want to put to a certain power element wise. But I have the following error :

TypeError: unsupported operand type(s) for ** or pow(): ‘ngsolve.bla.VectorD’ and ‘float’

What I aim to do is :

```
first = Integrate(5*test_function(u) ** exp, mesh, element_wise=True)**(1/exp -1)
```

Do you have any clue on how I can achieve this ?

Thank you for any help you can provide !
