Question

12ad to the third power and which term are like terms?

Answer 1

$(12ad)^{3}=12^{3}a^{3}d^{3}\\\\=1728a^{3}d^{3}$

There is only one term here. There are no like terms.

"Like terms" is a concept that applies to 2 or more terms that have the same constellation of variables (same variables to same powers).
