Certainly! Let's walk through the steps for each case provided:
### Case 1: 4812
To find the digit sum of 4812, we simply add the digits together:
[tex]\[ 4 + 8 + 1 + 2 = 15 \][/tex]
So, the digit sum of 4812 is 15.
### Case 2: [tex]$2.132=6$[/tex]
This doesn't fit typical rules for digit sums, so we'll consider it a given result.
### Case 3: 356
To find the digit sum of 356, add the digits together:
[tex]\[ 3 + 5 + 6 = 14 \][/tex]
So, the digit sum of 356 is 14.
### Case 4: 45072
To find the digit sum for 45072, add the digits together:
[tex]\[ 4 + 5 + 0 + 7 + 2 = 18 \][/tex]
So, the digit sum of 45072 is 18.
### Case 5: 78540
To find the digit sum for 78540, add the digits together:
[tex]\[ 7 + 8 + 5 + 4 + 0 = 24 \][/tex]
So, the digit sum of 78540 is 24.
### Case 6: 8347251
