Answer:
Last two digits = 42
Explanation:
1941^3843
first take last two digit 41
first last digit is 1
then take the 4 (1941) and multiply with 3 (3843)
4*3=12,take last digit from this is 2
now (1)(2)
so last two digit is 21
now same for 1961^4181
first take last two digit 61
first last digit is 1 ..............(1)
then take the 6 (1961) and multiply with 1 (4181)
6*1=6,take last digit from this is 2 ...........(2)
now (1)(2)
so last two digit is 61
last two digits of (1941^3843)+(1961^4181) is 61+21 = 82
That's the final answer.
