Explicație pas cu pas:
A = (25³)⁹ : (4²+3²)²⁶ - (2017⁰+0²⁰¹⁷+1²⁰¹⁷)⁴
A = 25³ˣ⁹ : (16+9)²⁶ - (1+0+1)⁴
A = 25²⁷ : 25²⁶ - 2⁴
A = 25²⁷⁻²⁶ - 16
A = 25-16
A = 9
B = 2⁷ - 11·{91-5·[22-5·(40²-41·39)]} + (3²-2³)²⁰¹⁷
B = 2⁷ - 11·{91-5·[22-5·(1600-1599)]}+(9-8)²⁰¹⁷
B = 128 - 11·{91-5·[22-5] + 1²⁰¹⁷
B = 128-11·[91-5·17]+ 1
B = 128-11·(91-85) + 1
B = 128-11·6 + 1
B = 129-66
B = 63
B > A
