Unit digit of the square of 13692

Here we will show you two ways of finding the unit digit of the square of 13692. First, we will define what the unit digit of the square of 13692 means. Next, we will find the unit digit of the square of 13692 using the Rule Method, and then we will find the unit digit of the square of 13692 using the Math Method.

The last digit (one digit) of the product you get when you multiply 13692 by itself is the unit digit of the square of 13692.

Rule Method
The unit digit of any square will never be 2, 3, 7, or 8. It can be only 0, 1, 4, 5, 6, or 9. Furthermore, the unit digit of the square of a number depends on its units digit. In other words, the unit digit of the square of 13692 depends on 2, because that is the last digit in 13692. Here are the rules:

Rule A) If the unit digit of a number is 0, then the unit digit of the square of that number is 0.

Rule B) If the unit digit of a number is 1 or 9, then the unit digit of the square of that number is 1.

Rule C) If the unit digit of a number is 2 or 8, then the unit digit of the square of that number is 4.

Rule D) If the unit digit of a number is 5, then the unit digit of the square of that number is 5.

Rule E) If the unit digit of a number is 4 or 6, then the unit digit of the square of that number is 6.

Rule F) If the unit digit of a number is 3 or 7, then the unit digit of the square of that number is 9.

The unit digit of 13692 is 2, therefore Rule C applies, and the unit digit of the square of 13692 is 4.

Unit digit of the square of 13692 = 4

Math Method
The unit digit of the square of a number depends on its units digit with this method too. Here you multiply the unit digit of the number by itself, and then look at the unit digit of that product. Again, the unit digit of 13692 is 2, so you multiply 2 by itself, and then look at the unit digit to get the answer once again:

2 × 2 = 4
Unit digit of 4 is 4.
Unit digit of the square of 13692 = 4

Of course, instead of using either of the methods above, you can multiply 13692 by itself if you have the time or a calculator, and then identify the unit digit to get the answer to the unit digit of the square of 13692. We did that below to double-check that our answer is correct:

13692 × 13692 = 187470864
Unit digit of 187470864 is 4.
Unit digit of the square of 13692 = 4
