**Square Root of 16**

If you are wondering what the square root of 16 is, it is exactly 4. The square root of a number (16 in this case) is a value that, when multiplied by itself, equals the original number (16). Mathematically, the square root of 16 can be expressed in either radical or exponent form:

-Radical form of the square root of 16: √16

-Exponent form of the square root of 16: 16^(1/2) or 16^(0.5)

The mathematical symbol √ is commonly known as the radical sign or radix. The number for which we are calculating the square root is known as the radicand, and it is the number that appears under the radical sign (radix).

**What is the square root of 16?**

The square root of 16 is a number which multiplied by itself equals 16. Therefore, the square root of 16 is exactly 4, since 4 x 4 = 16.

Therefore,

Therefore,

**ANSWER:**The square root of 16 is equal to 4, which can be represented as √16 = 4.**Is 16 a Perfect Square?**

Numbers that can be obtained by squaring a whole number, which is also referred to as an integer, are known as perfect squares. Integer values such as 0, 1, 2, 3, 4, 7, 8, and 9 are all classified as whole numbers. In contrast, numbers such as -5, 7.025, or 5 ½ are not regarded as whole numbers. It's worth noting that to obtain the square of a number, you multiply it by itself. For example, 81 is a perfect square because it is a product of 92 which is the same as 9×9. It is important to note that 9 is an integer, meaning it is a whole number without any fraction or decimal component.

In our case, 16 is a perfect square because it is the product of 4x4, which are both integers.

In our case, 16 is a perfect square because it is the product of 4x4, which are both integers.

**ANSWER:**16 is a perfect square.**Does the square root of 16 belong to the category of rational or irrational numbers?**

A number that can be represented as the quotient of two integers is considered a rational number. An integer, synonymous with whole number, is characterized by the absence of any fractional component. In simpler terms, a number is classified as rational if it can be represented as a fraction.

In the case of the square root of 16, the resulting value is a whole number and can be expressed as a fraction, namely 4/1. Hence, the square root of 16 is categorized as a rational number.

In conclusion, the square root of 16 is classified as a rational number.

In the case of the square root of 16, the resulting value is a whole number and can be expressed as a fraction, namely 4/1. Hence, the square root of 16 is categorized as a rational number.

In conclusion, the square root of 16 is classified as a rational number.

**Principal square root of 16**

Each positive number has two square roots, one of which is positive, and the other is negative. For example, the square roots of 16 are -4 (negative) and +4 (positive) because (-4)^2 = (+4)^2 = 16. The square root that is positive is referred to as the "principal square root." Typically, when we calculate "the square root of a number," we are referring to the principal square root.

In the case of 16,

In the case of 16,

**the principal square root is +4 or √16, which is written as √16.**
