Question

Sqare root of 7621 by long division

Answer 1

Answer:

Step I: Group the digits in pairs, starting with the digit in the units place. Each pair and the remaining digit (if any) is called a period.

Step II: Think of the largest number whose square is equal to or just less than the first period. Take this number as the divisor and also as the quotient.

Step III: Subtract the product of the divisor and the quotient from the first period and bring down the next period to the right of the remainder. This becomes the new dividend.

Answer 2

Answer:

HEY .....(^_^)

√3 + √2 / √3 - √2

= (√3 + √2 / √3 - √2 ) × ( √3 + √2 / √3 + √2)

= (√3 + √2)^2 / (√3)^2 - (√2)^2

= [ (√3)^2 + (√2)^2 + 2×√3×√2 ] / 3-2

= 3 + 2 + 2√6 / 1

= 5 + 2√6 explanation:
