Method 1 is to use general formula.

Method 2, which I will not write here, is plain expansion from the first term all the way until you obtain the a^4 b^4.

Thank you! I was kind of doubting if it was term 4 or term 5. Thanks for clearing it up!

The middle term a^4 times b^4 will be nicely the middle of the 9-term expansion, which will be the fifth term.
