First, multiply 28 by 28 and you get 784. Then multiply 784 by 28 and you get 21,952. The digit in the units place would be in the ones. This is 2. (If it were asking for the digit in the tens place, it would be 5, hundreds is 9, and so on.)
..20,000..........ten thousands
....1,000..........thousands
.......900..........hundreds
.........50..........tens
...........2..........units (or ones)
but you drop the zeros because they are asking for a single digit.

It means: what is the last number of the answer. So you don't need to do the whole multiplication. To begin with, consider the last number of 28 x 28. You only need to worry about the last number. This will be the same as the last number of 8 x 8 (=64) ie 4. Then if you multiply 4 by the final 28, this will end in the same as 4 x 8 (=32) ie 2, which is your answer.

The question is asking for you to find the digit that is in the "ones place" of the result of that multiplication. When you multiply those three numbers into a calculator, it will be the number all the way to the right. The digit go (right to left) 'ones' 'tens' 'hundreds' and so on...."units" is the same as "ones".

When you multiply 28x28x28=21,952, the units digit is the digit in the ones place or 2.
