Compute 221_3 + 122_3 + 202_3 + 110_3 in base 3.

Answer 1

To compute the sum in base 3, we add the numbers together in base 3.

221_3
+ 122_3
+ 202_3
+ 110_3

First, add the numbers column by column:
1+2+0+0 = 3 (which is equal to 10 in base 3)
2+2+0+1 = 5 (which is equal to 12 in base 3)
2+1+2+1 = 6 (which is equal to 20 in base 3)
2+2+2+0 = 6 (which is equal to 20 in base 3)

Therefore, the sum in base 3 is 2060.
