Are those "binomial coefficients"? If so, just use the definition of "binomial coefficients" to xpand each one. If theoy are not, then you will have to tell us hat they mean before we can help!

I picked that problem out of my excercise book. It asks me to expand the binomials into the form of a series

But I see no series only multiplication
