You need to evaluate the indefinite integral, such that:

`int (root(4)(x^3) + 1) dx = int root(4)(x^3) dx + int dx`

You may use the following formula `int x^n dx = (x^(n+1))/(n+1) + c`

`int root(4)(x^3) dx = int x^(3/4) dx = (x^(3/4+1))/(3/4+1) + c`

`int x^(3/4) dx = (4/7)*(x^(7/4)) + c`

Gathering all the results yields:

`int (root(4)(x^3) + 1) dx = (4/7)*(x^(7/4)) + x + c`

Hence, evaluating the indefinite integral, yields `int (root(4)(x^3) + 1) dx = (4/7)*(x^(7/4)) + x + c.`
