7.5.9.45.12.85=14458500

a)A=(1+3+3²+3³⁾+............+(3⁸+3⁹+3¹⁰+3¹¹)

A=1(1+3+9+27)+..............+3⁸(1+3+9+27)

A=1.40+...................+3⁸.40

A=40.(1+.......+3⁸)

Từ trên ta kết luận A chia hết cho 40

b) B=16⁵+2¹⁵=(2⁴)⁵+2¹⁵=2²⁰+2¹⁵=2¹⁵.2⁵+2¹⁵=2¹⁵.(2⁵+1)=2¹⁵.33

Do đó B=2¹⁵.33 chia hết cho 33 hay 16⁵+2¹⁵ chia hết cho 33
