Question

Chung to rang: 16^5 + 2^15 chia het cho 33

Answer 1

Ta thấy: 16^5=2^20 
=> A=16^5 + 2^15 = 2^20 + 2^15 
= 2^15.2^5 + 2^15 
= 2^15(2^5+1) 
=2^15.33 
số này luôn chia hết cho 33

Answer 5

16^5+2^5

=(2^4)^5+2^15

=2^4.5+2^15

=2^20+2^15

=2^15.2^5+2^15.1

=2^15.(2^5+1)

=2^15.(32+1)

=2^15.33⋮33
