8*10^k + j
8 multiplied by any power of 10 (0 - infinity) will always give remainder 8 when divided by 9
thus in this case, it's the value of j that will determine the remainder and not the value of k. Rather, the equation is independent of k.
Thus we can determine the value, just by having the value of j.
Thus the choice is B
:twisted:
Once we've rephrased the target question as, "What is the value of j?", we can see that the correct answer must be B.
