Hey could anybody help me differentiate this:

y = x + 3 + 8/x^4 (x^4 meaning x to the power 4)

I got an answer, which is -24x^-5 +1 however I am not confident with it and I am fairly certain it's wrong

Thanks for any help!

Yes, you are slightly wrong, its 1 -32x^-5
because -4 times 8 is -32 not -24 :P.

Multiply by the power, and then reduce the power by 1.
