Unit digit of the square of 26034

Here we will show you two ways of finding the unit digit of the square of 26034. First, we will define what the unit digit of the square of 26034 means. Next, we will find the unit digit of the square of 26034 using the Rule Method, and then we will find the unit digit of the square of 26034 using the Math Method.

The last digit (one digit) of the product you get when you multiply 26034 by itself is the unit digit of the square of 26034.

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 26034 depends on 4, because that is the last digit in 26034. 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 26034 is 4, therefore Rule E applies, and the unit digit of the square of 26034 is 6.

Unit digit of the square of 26034 = 6

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 26034 is 4, so you multiply 4 by itself, and then look at the unit digit to get the answer once again:

4 × 4 = 16
Unit digit of 16 is 6.
Unit digit of the square of 26034 = 6

Of course, instead of using either of the methods above, you can multiply 26034 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 26034. We did that below to double-check that our answer is correct:

26034 × 26034 = 677769156
Unit digit of 677769156 is 6.
Unit digit of the square of 26034 = 6
