Step 1: (1941^3843)
Take last two digit 41 from 1941 and raise it to the unit digit power 3 from 3843. (i.e) 41^3 = 68921. From this take only the last two digit 21.
Step 2: (1961^4181)
Take last two digit 61 from 1961 and raise it to the unit digit power 1 from 4181. (i.e) 61^1=61.
Step 3:
Add that 21 + 61 = 82
