E.g. 2. Use the knowledge on odd numbers to determine the square root of perfect numbers. (i) Determine the square root of 49. Think subtract the consecutive odd numbers starting from 1 from 49 until the remainder is zero. Then count the number of odd numbers subtracted as the square root of the given number.
