namasthe am selle dillon i wish to inform you Here the trick to find the square root of those numbers which are perfect squares only quickly Then it will be 2 sets starting from left ., Therefore answers will be 5|7 = 57 ., 5*6 = 30 which less than 32 ., Step 3: Since last digit of ’3249‘ ‘9‘ ., Instead we can solve them mentally by using tricks ., Now we have to find whether it 4 or 6 ., So right part of answers will be 3 or 7 ., Step 4: Our answers will be X|Y .,

For example 256 can be divided in two sets as 56 and 2 ., So the number remaining ’243′ ., And the numbers given corresponding to 6 under number column are 4 and 6 ., So left part of answers will be ’15′ ., Step 3: Since last digit of 24336 6 ., For that, multiply left part answers with 1 added in it means multiply 15 with 16 ., So ignore 25 ., It means right part answers will be bigger of 3 or 7 which 7 ., That number 5 ., Solution: Step 1: First we need to ignore last two digits of 24336 ., That number 15 ., Now we have to find whether it 3 or 7 ., Therefore right part ® of our answers will be ’5′ ., The number remaining ’32′ .,

Step 4: Our answers will be X|Y ., To solve this type of questions, we creates multiple sets of the given number taking two at a time starting from right ., Note: if the multiplication of left part answer*(left part answer+1) comes to be greater than left part of question given number, then the right part answers will be smaller of the [last digit to square] ., For example: 2025 can be divided into 20 and 25 ., If we make sets of four digit numbers ., Step 3: Since last digit of ’2025‘ ‘5‘ ., There are two 6 given in last digit to square column ., For solving square roots of perfect square numbers we don’t need to solve them through traditional method of solving ., It means right part answers will be bigger of 4 or 6 which 6 ., The number remaining ’20′ ., Step 2: Now from the above table, find square of a number which less than and nearest to 243 ., If it a three digit number, then we make two sets as FirstThe last two numbers Secondthe remaining number ., Therefore answers will be 4|5 = 45 .,

Below an example ., So left part of answers will be ’5′ ., Example 1 ., Solution: Step 1: First we need to ignore last two digits of 3249 ., Solution: Step 1: First we need to ignore last two digits of 2025 .,

So the square root of √2025 = 45 Example 2: Find the square root of 3249 ., For calculating the square root of numbers,

you need to learn the below given tables as it will let you solve square root questions quickly.

NUMBER SQUARE LAST DIGIT OF SQUARE 0 0 0 1 1 1 2 4 4 3 9 9 4 16 6 5 25 5 6 36 6 7 49 9 8 64 4 9 81 1

We will follow the steps given in below examples to find the Square root of a number:

Suppose we want to find the square root of 2025 ., Therefore answers will be 15|6 = 156 ., So here the trick which will let you solve square root of numbers which are perfect squares ., So from the tables given above, find 6 in last digit to square column ., For that, multiply left part answers with 1 added in it means multiply 5 with 6 ., So ignore 49 ., Step 2: Now from the above table, try to find square of a number which less than and nearest to 32 ., Find square root of 2025 ., Example 3: Find the square root of 24336 ., Step 4: Our answers will be X|Y ., So ignore 36 ., That number 4 ., So left part of our answers will be ’4′ ., So right part of answers will be 4 or 6 ., ., 15*16 = 240 which less than 243 (always compare with left part) ., Step 2: Now from the above table, try to find square of a number which less than and nearest to 20
