If the degree of monomial - 2 ^ 2XY is m and the number of terms of polynomial - AB ^ 3-2a ^ 2B + 3A ^ 3b is n, then - m ^ n=---------

If the degree of monomial - 2 ^ 2XY is m and the number of terms of polynomial - AB ^ 3-2a ^ 2B + 3A ^ 3b is n, then - m ^ n=---------

The degree of monomial - 2 ^ 2XY is m
∴m=2
The number of terms of polynomial-ab ^ 3-2a ^ 2B + 3A ^ 3b is n
∴n=3
∴-m^n=-2³=-8
