If (3m-2) x2yn + 1 is a quintic binomial with a coefficient of 1, then M=______ ,n=______ .

If (3m-2) x2yn + 1 is a quintic binomial with a coefficient of 1, then M=______ ,n=______ .

From the meaning of the question, we get 3M − 2 = 12 + N + 1 = 5, the solution is m = 1n = 2, that is, M = 1, n = 2
