3.146264369941972 ^100 = 314.6264369941972
this is like how i was thaught maths on school i guess i dunno

Maybe you'll know how to do it after reading this little example
3^3 is 3x3x3=27, not 3*3=9

Are you allowed to round it to an integer? It should be 1 right I don't even math, kill me nowNeta wrote:
it's (√2+ √3)^100 so we should find integer first
(√2+ √3)^8 is 9602. so (√2+ √3)^8 's digit is 2.
Answer : 7
not the best way but pretty close so answer acceptNeta wrote:

(√2+ √3)^8 is 9602. so (√2+ √3)^8 's digit is 2.
and 2^x 's digit goes 2, 4, 8, 6, 2, 4, 8, 6 .....
so (√2+ √3)^96 is 6.
and (√2+ √3)^4 is 97.9897....
(√2+ √3)^96 = 6
6[(√2+ √3)^96's digit] * 97. 9897[(√2+ √3)^4] goes 587, 8382....
so digit is 7
Answer : 7

Third one, Insane diff.
if you don't round you get a completely different answer but the unit digit is still 7 I thinkNeta wrote:
here's some fix about solution.
(√2+ √3)^8 is not integer i got rounding off to the nearest integer
