Unit's place that has digits - 2/3/7/8
Then, unit's digit repeats every 4th value. Divide the power (or index) by 4.
After dividing,
If remainder is 1, unit digit of number raised to the power 1.
If remainder is 2, unit digit of number raised to the power 2.
If remainder is 3, unit digit of number raised to the power 3.
If remainder is 0, unit digit of number raised to the power 4.
effectively, three is raised to three and then two is added,
so (27+2)/5 the remainder should be 4.....whatsay??
