Create a function that finds the [integral](https://en.wikipedia.org/wiki/Integral) of the expression passed.
In order to find the integral all you need to do is add one to the `exponent` (the second argument), and divide the `coefficient` (the first argument) by that new number.
For example for `3x^2`, the integral would be `1x^3`: we added 1 to the exponent, and divided the coefficient by that new number).
Notes:
* The output should be a string.
* The coefficient and exponent is always a positive integer.
## Examples
```
 3, 2  -->  "1x^3"
12, 5  -->  "2x^6"
20, 1  -->  "10x^2"
40, 3  -->  "10x^4"
90, 2  -->  "30x^3"
```
def integrate(coefficient, exponent):
    return f'{int(coefficient/(exponent+1))}x^{exponent+1}'
def integrate(coefficient, exponent):
    return f'{int(coefficient/(exponent+1))}x^{exponent+1}'
