Given the function f(x) as shown below.


f(x)=\int_0^(x3)t^5dt

Simplify the integral


\int_0^(x3)t^5dt=\lbrack(t^(5+1))/(5+1)+C\rbrack_0^(x3)
\lbrack(t^(5+1))/(5+1)+C\rbrack_0^(x3)=\lbrack(t^6)/(6)+C\rbrack_0^(x3)
(((x^3)^6)/(6))-(0^6)/(6)
\therefore f(x)=(x^(18))/(6)

Thus, the derivative of f(x) is:


f^(\prime)(x)=(18* x^(18-1))/(6)=(18x^(17))/(6)=3x^(17)

Final answer


f^(\prime)(x)=3x^(17)
