You've done fairly well so far except...- You forgot the "log" in front of your answer
- Exponents do not distribute! IS NOT !!! And IS NOT .
So your answer should be:
or whatever you get if you correctly raise x+5 and x-3 to their respective powers.
If you feel you should multiply these out, look into using the binomial theorem. If you do not know how to use the Binomial Theorem, then just multiply (x+5)(x+5)(x+5)(x+5)(x+5) and (x-3)(x-3)(x-3) by hand.
