Consider the integral ∫x^4 (x^5-10)^6 dx.
To find the value of this integral, make the
substitution u=x^5 - 10.
a) Write (x^5-10)^6 in terms of u:
b) This makes x^4 dx =
c) Re-write the integral in terms of u and du, and
find the antiderivative.
The antiderivative in terms
of u is:
d) Now back-substitute and write your answer to part (c) in terms
of x:
