Solution:
In order to find the unit's digit of the square of any given number, we will have to find the square of the unit's digit of that number and it's unit's digit shall be the unit's digit of the square of the original number.
So, unit's digit of the square of 272 will be:
2² = 4
We can verify this as follows:
272² = 272 × 272 = 73,984
Thus, unit's digit of square of 272 is 4.
