Quote: When you simplify ,3 to the 56 power what number is in the ones place
well let's take a look
3 9 27 81 243 729 2187 ...
so the last digit repeats as
1 2 3 4 5 6 7 8 (power)
3 9 7 1 3 9 7 1 ...
so
3^(4n+0) -> 1
3^(4n+1) -> 3
3^(4n+2) -> 9
3^(4n+3) -> 7
56 = 4*14 + 0
so 3^56 will end in 1
+6248
