How would you describe a square root?
A square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. The symbol is √ which always means the positive square root.
What is a perfect square in square roots?
A square root is the number that, times itself, produces a given number. Perfect squares are numbers whose square roots are whole numbers. These numbers are perfect squares: 4, 9, 16, 25, 36. When you look at their images, you can see why.
How do you describe numbers that are perfect square?
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words, it is the product of some integer with itself. For example, 9 is a square number, since it equals 32 and can be written as 3 × 3. The unit of area is defined as the area of a unit square (1 × 1).
What is a square and square roots?
Squares are the numbers, generated after multiplying a value by itself. Whereas square root of a number is value which on getting multiplied by itself gives the original value. Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.
What is the meaning of perfect square?
A perfect square is a number, from a given number system, that can be expressed as the square of a number from the same number system. Examples of Numbers that are Perfect Squares. 25 is a perfect square. 25 is a natural number, and since there is another natural number 5, such that 52 = 25, 25 is a perfect square.
How do you explain square root transformation?
a procedure for converting a set of data in which each value, xi, is replaced by its square root, another number that when multiplied by itself yields xi. Square-root transformations often result in homogeneity of variance for the different levels of the independent variable (x) under consideration.
What is the perfect square of √ 21?

What is the difference between a perfect square and a square root?
A square root is the number that, times itself, produces a given number. Perfect squares are numbers whose square roots are whole numbers. When you look at their images, you can see why. These numbers are perfect squares because their square roots are whole numbers.
How do you describe the relationship of a square root?
A square root relation(ship) corresponds to a square root formula. Because the square root of a negative number does not exist (unless you are working with complex numbers), the graph will not exist there either. In almost all cases when working with square root formulas you have a certain domain and range.

How do you know if there is a perfect square root?
If a number is a perfect square number, then there exists a perfect square root. If a number ends with an even number of zeros (0’s), then it can have a square root. The two square root values can be multiplied. For example, √3 can be multiplied by √2, then the result should be √6.
What is the difference between the square and the square root?
The Square of a number is the value of power 2 of the number, while the square root of a number is the number that we need to multiply by itself to get the original number. If a is the square root of b, it means that a×a=b.
How to find the square root of a whole number?
If the square root of n is a, then a multiplied by a is equal to n. It can be expressed as: This is the formula for square root. The perfect squares are the one whose square root gives a whole number. For example, 4 is a perfect square because when we take the square root of 4, it is equal to 2, which is a whole number.
What is an example of a perfect square?
Perfect squares are the numbers, the square root of which gives a whole number. For example, 9 is a perfect square, because its root is a whole number, i.e.√9 = 3. What is an imperfect square with examples?
