Question

Evaluate the indefinite integral:

Answer 1

\[\int\limits_{?}^{?}x^4\sqrt{12+ x^5}sx\]

Answer 2

ignore the question marks

Answer 3

Okay , you can take the following:\[u= x^5 + 12\]\[du = 5x^4dx\]

now you'll get the following:
\[=1/5 \int\limits_{}^{}\sqrt{u} du\]

You can proceed from here ^_^

Answer 4

if you still can't solve it, let me know :)

Answer 5

yeah i'm still kind of stuck :/

Answer 6

\[1/5\int\limits_{}^{}\sqrt{u} du =1/5\int\limits_{}^{}^{}^{} u ^{1/2} = 1/5*2/3u ^{3/2} + C \]
Now plug in u.

Answer 7

lol, thank you DE ^_^
