Brain Teaser Math Trick -Quickest Way To Find The Square Root Of Any Number- Solution
If you people are still trying to get the answer to this brain teaser puzzle, we have come up with the answer to this Maths puzzle.
Don’t scroll down to know the answer, just take a few minutes and analyze the question. We hope you people can answer this brain teaser puzzle.
If not still, you are struggling to get the brain teaser answer. Apply the rules that appear after first determining the individual values of the numbers you see to arrive at the solution to this brain teaser.
How many of you were able to find the solution to this brain teaser puzzle? Let’s see.
We have listed the answer below.
First Method
The square root of a number is the inverse operation of the square of a number. Example Number Square of the number Square root of the number 6^2 6 × 6 = 36 √36=6 8^2 8 × 8 = 64 √64=8 12^2 12 × 12 = 144 √144=12 Points to be remembered before finding the square root of any number: 1.
Second Method
The number is arranged as a group of two numbers from right to left. If a single number remains on the left, it is also considered one group. 2. The number of groups derived for the given number will be the number of digits of the square root of that number.
Example: √25=5, here there are two digits, so one group.
So, the square root of 25 is 5. √169=13, the number forms two groups (1, 69), so the square root is a two-digit number 13. 3.
If the square of a number is an odd number, then the square root is also an odd number, and if the square is an even number, then the square root is also an even number.
Logic to find the square root Observing the square of numbers from 1 to 9, we can analyze that an exact square ends with 1,4,5, 6,9, and 0 square roots.
These numbers will be rational numbers. If the square of the number ends with 2,3,7, and 8, then its square root will be an irrational number.
The square root of a perfect square number: Number:√3969 Step 39 | 69 Grouping: from right to left, 38 is greater than 36, the perfect square number of 62, and 69 is lesser than 64, which is a perfect square number of 82 3600 | 6400 602 | 802.
Therefore the given number lies between 3600 and 6400, which means their square number will be between 60 and 80. So, the first number in the square root will be 6. The number in the units places is 9, so the square number should be ending with 3 or 7 (as discussed above) . The square root of the given number should be either 63 or 67. Applying digit sum method to find the square root 63 = 3969 (6 + 3) = 3+9+6+9 9 = 2 + 7 9 = 9, So the square root of the number 3969 is 63 Answer: 3969 = 63 Square root of an imperfect square number: Number Steps √2 The given number is not a perfect square 1 + 1 = 2. or 4 - 2 = 2 The nearest square number is 1 and 4 1 + 1/2 1 + 0.5 1.5 Square root of 1 is 1, add (1 ÷ [ 1 + 1]) i.e. 1 divide by twice the perfect square number 1.5 The same when calculated in calculator gives 1.414 which is approximately equal to 1.5 √20 √2 25 - 5 = 20 25 is the perfect square of 5 subtract it from (1/10) 1 divide by twice the perfect square 25 - 5/10 5 - 0.5 4.5 The same when calculated in calculator gives 4.47 which is approximately equal to 4.5
After learning a few of the tricks to find square and square roots of the number, one can easily find the square numbers and their square roots without help from calculators. These tricks are very helpful in solving aptitude problems related to square and square roots in competitive exams.
This brain teaser is a great way to test your math skills and your sharpness. The above brain teaser answer is the right way to answer this puzzle. You need unique thinking and a creative mindset to solve these brain teasers. There are a number of types of brain teasers, including riddles, picture puzzles, and logic puzzles.
