ab + 8ab = ab + 800 + ab = (2. ab - 1) + 801 

Để ab + 8ab chia hết cho 9 thì 2.ab - 1 chia hết cho 9 (do 801 chia hết cho 9)

=> 2.ab - 1 -9 = 2.ab - 10 chia hết cho 9 

Hay 2. (ab - 5) chia hết cho 9 => ab - 5 chia hết cho 9 (do (2;9) = 1   )

=> ab - 5 \(\in\) {9;18;27;36;45;...;90}

=> ab \(\in\) {14;23;...; 95}
