Which term can be added to the list so that the greatest common factor of the three terms is 12h3?36h3, 12h6, __________

The existing terms, 36h³ and 12h⁶, have a greatest common factor of 12h³. To keep that GCF after adding a term, its coefficient must be divisible by 12 and its exponent of h must be at least 3. The term 48h⁵ meets both conditions, so the answer is 48h⁵.
