Question 2.3: Convert 10410 to base 3 using the division-remainder method.

3 ⌊104 2 3 divides 104 34 times with a remainder of 2
3 ⌊34 1 3 divides 34 11 times with a remainder of 1
3 ⌊11 2 3 divides 11 3 times with a remainder of 2
3 ⌊3 0 3 divides 3 1 time with a remainder of 0
3 ⌊1 1 3 divides 1 0 times with a remainder of 1
0
Reading the remainders from bottom to top, we have: 104_{10} =10212_{3}
