Square root of 9
Precisely 3 is the value of the square root of 9. When we calculate the square root of a number (9 in this case), we get a value (3 in this case) that, when multiplied by itself, results in the original number (9). The square root of 9 can be expressed in two different forms: radical or exponent:
-Radical form of the square root of 9: √9
-Exponent form of the square root of 9: 9^(1/2) or 9^(0.5)
The symbol √ is commonly referred to as the radical sign or radix. The number that is being evaluated for its square root is known as the radicand, which is the number situated beneath the radical sign (radix) in this scenario.

What is the square root of 9?
A number that, when multiplied by itself, results in 9, is referred to as the square root of 9. Therefore, the square root of 9 is 3 and we write it √9=3 because 3=9. Since 3 is the same as 3 x 3 the following expression is true:
9 = 3=3×3
Therefore
ANSWER: square root of 9=√9=3
9 = 3=3×3
Therefore
ANSWER: square root of 9=√9=3
Is 9 a Perfect Square?
A number is defined as a perfect square if it can be expressed as the result of squaring a whole number (also known as an integer). Whole numbers include 0, 1, 2, 3, 4, 7, 8, and 9, whereas numbers such as -9, 7.025, or 5 ½ are not considered whole numbers. When you multiply a number by itself, you can find its square. For instance, 81 is a perfect square because it can be obtained by squaring 9, which is 9 multiplied by itself (9×9). It's important to note that 9 is a whole number (integer).
Our example shows that 3 is the square root of 9. Since 3 is a whole number, therefore 9 is a perfect square.
ANSWER: 9 is a perfect square
Our example shows that 3 is the square root of 9. Since 3 is a whole number, therefore 9 is a perfect square.
ANSWER: 9 is a perfect square
Is the square root of 9 rational or irrational number?
A number is considered rational if it can be expressed as a quotient or ratio of two integers. An integer, also known as a whole number, does not have a decimal or fractional part. In other words, a number is rational if it can be written in the form of a fraction.
One way to determine whether 9 is a perfect square is to check if its square root is a rational or an irrational number. All perfect squares have rational square roots, while the square roots of non-perfect squares are irrational. As we know that 9 is a perfect square, we can conclude that its square root is a rational number.

Principal square root of 9
Every positive number has two square roots, one positive and the other negative, such as the square root of 9, which has two roots, -3 (negative) and +3 (positive), as both (-3)^2 and (+3)^2 are equal to 9. The positive square root is typically referred to as the "principal square root," and when we calculate the square root of a number, we usually mean the principal square root. In this case, the principal square root is +3, represented as √9=3. A number without a minus (-) sign is positive.
Therefore, the principal square root of 9 is √9=3.
Therefore, the principal square root of 9 is √9=3.
