SUMMARY
The 15th term of the expansion of (X3 + Y)25 can be determined using the binomial theorem. According to the theorem, the general term in the expansion is given by Tk = C(n, k) * (an-k) * (bk), where C(n, k) is the binomial coefficient. For this specific case, the 15th term corresponds to k = 14, resulting in T15 = C(25, 14) * (X3)11 * Y14.
