As a result, the number becomes 52, and when we divide it by 2 again, we get 26. Since 26 is now an even number, it can once more be divided by 2. So we will left with 13
Which means that

We are aware that if we square root both sides, the numbers that occur twice will only emerge from the root once.
Which means that

Hence, we are left with

Now we know the value of
