If XY denotes X is raised to the power Y, Find the last two digits of 19413846+ 19614181
If XY denotes X is raised to the power Y, Find the last two digits of 19413846+ 19614181
Answer/Solution
82
Steps/Work
1941^3846
unit digit= 1^4=1
10th digit=4*6=24=2 means last two digit =41
and 1972^4181
unit digit=1
10th digit=7*2=14 mean last two digit= 41
hence,
41+41= 82
unit digit= 1^4=1
10th digit=4*6=24=2 means last two digit =41
and 1972^4181
unit digit=1
10th digit=7*2=14 mean last two digit= 41
hence,
41+41= 82
