The square root of 225, found using the successive subtraction method, is 15.
The successive subtraction method involves repeatedly subtracting consecutive odd numbers from the original number until you reach zero. The number of subtractions performed gives you the square root. According to the reference, starting from 225, after subtracting consecutive odd numbers 15 times, we obtain 0. Therefore, the square root of 225 is 15. This method can be valuable for understanding the underlying principles of square roots.
