Question

I need help to; Use intergration by parts to evaulate the integral ∫ (x) √4:(x+7)dx

Answer 1

\[x \sqrt[4]{x+7}\]

Answer 2

u=x+7

Answer 3

no need to use parts

Answer 4

Why wouldn't you use parts

Answer 5

if u=x+7 then x=u-7

du=dx

\[\int x \sqrt[4]{x+7}dx=\int(u-7)u^{1/4}du=\int\left(u^{5/4}-7u^{1/4}\right)du=\cdots\]
