Answer:
All are the correct ordered pair
Step-by-step explanation:
At the place of a we can put anything as the divisibility rule of 8 depends on the last three digits, In this case the last three digits are 3b4 , if 3b4 is divisble by 8 then the whole no. will be divisible by 8. We will put the value 0 , 4 and 8 and then see which are divisible and which are not and we will find that all of them are divisible
