Special Division Method for Square Roots

In this video, Anil Kumar demonstrates a special division method to find the square roots of irrational numbers, specifically square roots of 2 and 3, to three decimal places. The method involves using the same number as both the divisor and quotient, and doubling the quotient for the next divisor. The video provides a detailed, step-by-step calculation for each square root, emphasizing the importance of using three sets of zeros for precision. The video concludes with a recap of the method and encourages viewers to practice the steps independently.

What is the purpose of the special division method introduced in the video?

• To divide rational numbers

• To find the square roots of rational numbers

• To multiply irrational numbers

• To calculate the square roots of irrational numbers to three decimal places

When calculating the square root of 2, how many sets of zeros are used?

• Three sets of zeros

• One set of zeros

• Two sets of zeros

• Four sets of zeros

In the special division method, what is the relationship between the divisor and the quotient?

• The divisor is unrelated to the quotient

• The divisor and the quotient are the same

• The divisor is double the quotient

• The divisor is half of the quotient

What is the next step after finding the initial divisor in the square root of 2 calculation?

• Subtract the divisor from the original number

• Add a new number to the quotient

• Multiply the divisor by 3

• Bring down another set of zeros

What is the final result for the square root of 2 to three decimal places?

• 1.618

• 1.500

• 1.732

• 1.414

How is the initial divisor determined when calculating the square root of 3?

• By dividing by 2

• By using the number 3

• By using the number 1

• By doubling the number 3

What is the first step in the special division method for square root of 3?

• Divide 3 by 2

• Divide 3 by 1

• Multiply 3 by 1

• Subtract 1 from 3

What is the final result for the square root of 3 to three decimal places?

• 1.414

• 1.732

• 1.500

• 1.618

What is the next step after doubling the quotient in the square root of 3 calculation?

• Add a new number to the quotient

• Bring down another set of zeros

• Subtract the divisor from the original number

• Multiply the divisor by 3

What is the key concept behind the special division method for finding square roots?

• Subtracting the divisor from the original number

• Multiplying the divisor by 3

• Using the same number for divisor and quotient

• Using different numbers for divisor and quotient
