Square root of 49
If you are wondering what the square root of 49 is, it is exactly 7. Similar to the square root of other numbers, the square root of a number (49 in this case) is a value that, when multiplied by itself, results in the original number (49). Mathematically, the square root of 49 can be expressed in either radical or exponent form:
-The radical form of the square root of 49 can be expressed as √49.
-Exponent form of the square root of 49: 49^(1/2) or 49^(0.5)
The radical sign or radix is a symbol that is commonly represented as √. The radicand is the number for which we are calculating the square root, and it is located underneath the radical sign or radix.

ANSWER: Square root of 49 = √49 = 7
Is 49 a Perfect Square?
A perfect square is a number that is obtained when a whole number, also known as an integer, is squared, or multiplied by itself. Whole numbers are integers that include 0, 1, 2, 3, 4, 7, 8, and 9. For example, 81 is a perfect square since it can be expressed as 9², which is the same as 9 multiplied by 9. It should be noted that 9 is a whole number or an integer. Conversely, numbers such as -5, 7.025, or 5 ½ are not considered whole numbers.
In our example, the square root of 49 is a whole number, which means that 49 is a perfect square.
ANSWER: 49 is a perfect square.
In our example, the square root of 49 is a whole number, which means that 49 is a perfect square.
ANSWER: 49 is a perfect square.
Is the square root of 49 rational or irrational number?
An irrational number is a numerical value that cannot be represented as the quotient of two integers. In contrast to rational numbers, they cannot be expressed as a finite or repeating decimal.
In our case, the square root of 49 can be expressed as a ratio of two whole numbers, which means that it is a rational number.
ANSWER: The square root of 49 can be classified as a rational number.
In our case, the square root of 49 can be expressed as a ratio of two whole numbers, which means that it is a rational number.
ANSWER: The square root of 49 can be classified as a rational number.
Principal square root of 49
Two square roots are associated with every positive number, one positive and one negative. The positive square root is called the "principal square root," which is usually the one referred to when computing "the square root of a number."
In our case, the principal square root of 49 is exactly 7, which is written as √49 = 7.
It is important to note that the principal square root of a positive number is always positive. In the case of the square root of 49, both positive and negative 7 multiplied by themselves result in 49. However, we refer to the positive value of 7 as the principal square root.
The square root of 49 is a perfect square since it results from squaring the whole number 7. Perfect squares have rational square roots because they can be expressed as a ratio of two integers. As a result, the square root of 49 can be classified as a rational number.
