a = (2⁵)⁸ : 2³⁷ =2⁴⁰⁻³⁷=2³=8
b = 4¹⁹ ·4¹⁰ : (4⁴)⁷ =4¹⁹⁺¹⁰⁻²⁸=4¹=4
c = 2⁷· 3⁷ : 6⁵=6⁷⁻⁵=6²=36
(a+b+c)/3=(8+4+36)/3=48/3=16
a = ( 2 ^ 5 ) ^ 8 : 2 ^ 37
a = 2 ^ 40 : 2 ^ 37
a = 2 ^ 3
a = 8
b = 4 ^ 19 × 4 ^ 10 : ( 4 ^ 4 ) ^ 7
b = 4 ^ 29 : 4 ^ 28
b = 4 ^ 1
b = 4
c = 2 ^ 7 × 3 ^ 7 : 6 ^ 5
c = 128 × 2187 : 7776
c = 279936 : 7776
c = 36
Ma = ( a + b + c ) : 3 = ( 8 + 4 + 36 ) : 3 = ( 12 + 36 ) : 3 = 48 : 3 = 16
