please answer this question this is it correct choice it maybe one or two more than two answers also

Answer 1

option [a]

888222+222888≡3222+2888mod5888222+222888≡3222+2888mod5

Next, we need work out the period of 3 and 2 mod 5.

34≡1mod534≡1mod5 and 24≡1mod524≡1mod5

So, the period for both are 4.

888222+222888≡3222+2888≡34×55+2+24×222≡32+1≡0mod5888222+222888≡3222+2888≡34×55+2+24×222≡32+1≡0mod5

So, the answer is 0.
