C should be the answer. I think it's trying to trick you by switching up its order...
SO long as there is a "b" and an "a" not raised to any powers or have any "special add-ons" then 25ab and 5ba ARE, in fact, "like" terms.

Okay, do you know what like terms are? @cjackson2002

anonymous · Answer

not really

Alright, "like" terms are variables or numbers in a set that are identical. Like...
13+9a+6b+3a=?
You would look at every number or variable that is identical...
Which ones look the same?
