Question

Could someone check my work:
Find the Indefinite Integral...

Answer 1

\[\int\limits \frac{ 5t }{( t ^{2} + 4)^{5} } dt\]

Answer 2

so that was the question

Answer 3

Let u = t^2+4

Answer 4

here is my answer:

\[\frac{ -5 }{ 8(t ^{2} + 4)^{4} } + C\]

Answer 5

I was wondering if the 4 on the bottom (the exponent should be negative or not)
I figured since its on the bottom, the exponent 4 can me a positive since its in the denominator.
