Скачать или смотреть Square root by Long division method ( Basic of Mathematics)

This video provides a comprehensive tutorial on calculating square roots using the long division method (0:52), focusing on complex numbers, including those with decimals (0:31).

The tutorial breaks down the process into several key steps:
Pairing numbers (2:00): The first step involves grouping numbers into pairs from the right, or from the decimal point outwards for decimal numbers (17:57).
Finding the initial divisor (2:59): Select a number that, when multiplied by itself, is less than or equal to the first pair or single digit.
Subtracting and bringing down pairs (4:39): After subtracting, the next pair of numbers is brought down.
Doubling the quotient (5:17): The current quotient is doubled and used as the beginning of the new divisor.
Iterative process (6:44): Repeat the process of finding the next digit, multiplying, and subtracting until the remainder is zero or the desired precision is achieved.
Handling decimals (17:37): When dealing with decimals, a decimal point is added to the quotient as soon as the first pair after the decimal point is brought down (22:42).

The video demonstrates the method with several examples, starting with simple integers like 625 (1:23) and 9216 (8:32), and gradually moving to more complex decimal numbers such as 6773.29 (17:37), 404.01 (25:33), and 4357.3201 (30:10), to solidify understanding.
