a, A = 2+2²+2³+...+2¹⁰

A = (2+2²)+(2³+2⁴)+...+(2⁹+2¹⁰)

A = 2(1+2) + 2³(1+2) +.....+ 2⁹(1+2)

A = 2.3 + 2³.3 +....+ 2⁹.3

A = 3.(2+2³+...+2⁹) chia hết cho 3 (đpcm)

b, A = 2+2²+2³+...+2¹⁰

A = (2+2²+2³+2⁴+2⁵)+(2⁶+2⁷+2⁸+2⁹+2¹⁰)

A = 2(1+2+2²+2³+2⁴) + 2⁶.(1+2+2²+2³+2⁴)

A = 2.31 + 2⁶.31

A = 31.(2+2⁶) chia hết cho 31 (Đpcm)
