Question

Integrate

4/x^3 dx

Answer 1

\[\int\limits_{?}^{?}\frac{ 4}{ x^3 }\]

Answer 2

this is indifinite integral so limit is not given solution is x^(n+1)/ (n+1)

Answer 3

\[\int\limits_{}^{}4(x)^{-3}=4\int\limits_{}^{}(x)^{-3}=(x)^{-2}/-2\]

Answer 4

Close. You forgot the 4 in the final answer. So I think it should be

\[-2x ^{-2} +C\]

I don't recall if the C is relevant or not for this question.

Answer 5

oh your'e right, i missed the 4 and the constant( if the integral was indefinite).
