## Topics Covered in Exercise 5.4 Class 8 Mathematics Questions

Ex 5.4 class 8 maths chapter 5 NCERT solutions is about finding the square root using the division method and the square root of decimals. Here, you can find the detailed solutions for each topic.

 1 Finding square root by division method 2 Square Roots of Decimals
1. Finding square root by division method

Here are the Steps to find the square root by division method:

Step 1- First, we need to make the pair of digits from right and if there are odd number of digits, then the single number left at left will also have a bar.

Step 2- Find the largest number whose square is less than or equal to the number under the extreme left bar. Take this number as the divisor and the quotient with the number under the extreme left bar as the dividend. Divide and get the remainder.

Step 3- Bring down the number under the next bar to the right of the remainder.

Step 4- Double the quotient and enter it with a blank on its right.

Step 5- Guess 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 the product is less than or equal to the dividend.

Step 6-  If there are a large number of digits then you can repeat the steps 3, 4, 5 until the remainder does not become 0.

1. Square Roots of Decimals

In order to find the square root of a decimal number, we must apply bars to the primary part of the number as described above. For the numbers on the right side of the decimal, we need to put bars starting from the first decimal place.

The rest of the method is the same as above. All we have to do is add a decimal in between when the decimal will come in the division.

Question 1. How do you use the division method step by step?

Answer 1. The division method can be broken down into four operations: dividing, multiplying, subtracting and bringing down.

Step 1- Divide the given number by divisor by determining the suitable integer.

Step 2- To get the number you want to subtract from the dividend, multiply the divisor and integer.

Step 3- The number is then subtracted from the dividend.

Step 4-  Bring down the remainder and another digit (if any) from the dividend.

Step 5- Proceed with the above steps until the remainder is 0 or less than the divisor.
