M chia hết cho 5 không:
M=6+16+162+163+.........+168+169
Tính :
a) 3 + − 5 + − 1 + − 7
b) 16 + − 5 − − 16 + 4
a) 16 . 36 - 16 . 37
b) 36 : 4 . 3 + 9 . 50
c) 2 . (5 . 16 - 18) + 36 : 18 . 2
d) 48 : 8 . 5 + 5 . 44
e) 5 . 4 - 18 : 3
f) 2 . 25 + 169 : 13 - 54 : 27
Chứng tỏ A chia hết cho 5 biết A=6+16+162+163+........+168+169
