Answer 2

Concept

The square root of a number is basically the number of power 1/2.

Given

Number=2.61

To find

Square root of 2.61.

Explanation

We have been given a number be 2.61 and we have to find the square root of 2.61. We can write it as $(2.61)^{1/2}$

We can find it through long division method.

We have to group the digits into pairs to the left of the decimal point,pair them from the right to left and for digits after decimal point,pair them from left to right.

Now find the largest number whose square is less than or equal to the number in the leftmost group. Take this number as divisor and the quotient with the number in the leftmost group as the dividend. Divide and get the remainder. Put the decimal.Bring down the next pair 61. Add the divisor with  quotient and enter  with a blank on its right. Find a largest possible digit to fill the blank which will also become the new digit in the quotient, such that when the new divisor is multiplied to the new quotient so that the product is less than or equal to the dividend. In this case 26 × 6 = 156, so we choose the new digit as 6. Get the remainder. Now repeat the steps as discussed above and we will get quotient be 1.615. Rounded above we will get 1.62.
