### Subject: Calculus

Find the anti-derivative of 2/x^3.

To first approach the problem isolate the x value that will be anti-derived. Remember that 1/x = x^-1, so using this you can come to 2*x^-3. Finally using the anti-derivative rule x^n = x^n+1/n+1 you come to 2x^-2/-2, which can be simplified to -x^-2, which can be further simplified to -1/x^2, which is an answer. Another answer could be just leaving it at -x^-2
