What is the antiderivative of f(x)= 2x^8 + 10x^5 - 8x^4 - 4?

I got (2/9)^9 + (10/6)^6 - (8/5)^5 - 4x but it's not right.

Your answer is correct.

Check your second term, they probably reduced the 10/6 to 5/3

What happened to the x's in the first three terms?

The first term should be (2/9)x^9

You made similar errors in the second and third terms by not typing in the "x" before the exponent.

drwls is right.
I didn't even notice that you dropped the x's.

Oh dang. That's what I forgot. The x's. I put in the x's and the answer was correct. Thanks!
