If y
x denotes x raised to the power y , find the last two digits of   3843 1941 +   4181 1961 .
a. 02 b. 82 c. 42 d. 22

• 1941last 2 digits is 41 and unit digit is 3843 is 3
  41^3 is last 2 digits is 21 and next no is 61^1=61
  61+21=82

• 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
