Answer:
4x^3
Step-by-step explanation:
Choose p so that it's the derivative of x^4.
This would give us integral(e^u du) which is integratable over elementary functions....simply it is e^u+c.
Anyways, p=(x^4)' which gives 4x^3 by power rule.
Choose p(x)=4x^3 or a constant multiple of this would also suffice.
