√4 | 2 | Since 22 = 4 |
---|---|---|
√49 | 7 | Since 72 = 49 |
√64 | 8 | Since 82 = 64 |
√81 | 9 | Since 92 = 81 |
√100 | 10 | Since 102 = 100 |
How do you find the square root of a non perfect square number by division method?
Division Method. Take the number whose square root is to find. Place a bar over every pair of the digit of the number starting from that in unit’s place (rightmost side). We divide the leftmost number by the largest number whose square is less than or equal to the number under the leftmost bar.
How do you find the square root of a non perfect square without a calculator?
Finding square roots of of numbers that aren’t perfect squares without a calculator
- Estimate – first, get as close as you can by finding two perfect square roots your number is between.
- Divide – divide your number by one of those square roots.
- Average – take the average of the result of step 2 and the root.
What is non perfect square?
Please note that all the perfect square numbers end with 0, 1, 4, 5, 6 or 9 but all the numbers with end with 0, 1, 4, 5, 6 or 9 are not perfect square numbers. Example, 11, 21, 51, 79, 76 etc. are the numbers which are not perfect square numbers.

Before learning the procedure, it is wise that the performer memorizes the squares of the numbers 1-10 which is very elementary.
What is the mental square root algorithm for 661062?
Mental Square Roots Algorithm. 1 Step 1: Use your knowledge of square numbers to find the first two digits of the answer. For 661062, we see that 81² = 6561 < 6610 < 82² = 6724, so 2 Step 2: 3 Step 3: 4 Step 4: 5 Step 5:
What is the square root of a negative square root?
When two same square roots are multiplied, then the result should be a radical number. It means that the result is a non-square root number. For instance, when √7 is multiplied by √7, the result obtained is 7. The square root of any negative numbers is not defined.
How do you know if a square root is a radical number?
For example, √3 can be multiplied by √2, then the result should be √6. When two same square roots are multiplied, then the result should be a radical number. It means that the result is a non-square root number. For instance, when √7 is multiplied by √7, the result obtained is 7.
