Title: Indefinite Integral Exercise

So I noticed there are actually two other integral exercises being submitted at the moment. Oh well! Having to choose from multiple contributions is definitely a luxury problem. This is an indefinite integral exercise that tests the power and constant rule, and uses negative exponents and fractions.

I couldn't get MathJax to print a not-equal-to sign. How do I do that?
