First, heya!Now, this problem is pretty easy. All you have to do is multiply the coefficients together, multiply the exponents together, and then mash your two parts together to get the answer.The coefficient part is simple. 4/3 * 12 is equal to 48/3, or 16.The exponent part is a little less obvious, but you just add the exponents together to get t^5 [(t*t*t) * (t*t)].Mash your answer together and you get 16t^65
