Definition: Defining the square root as the value that, when multiplied by itself, gives the original number
The square root of a number is defined as the value that, when multiplied by itself, results in the original number. In other words, if we have a number x, its square root is denoted by the symbol √x. For example, the square root of 49 can be represented as √49.
Calculation: Determining the square root of 49 by finding the number that, when multiplied by itself, equals 49
To calculate the square root of 49, we need to find the number that, when multiplied by itself, equals 49. By applying this logic, we can determine that the square root of 49 is either a positive or a negative number.
Principle of Square Roots: Explaining the general concept of square roots and their role in mathematics
Square roots are an integral part of mathematics and are used to solve various problems. They serve as a means to find the original value of a number after it has been squared. The principle of square roots allows us to work backwards from the squared value to find the original number.
Positive Square Root: Identifying the positive value of the square root of 49, which is 7
In the case of the square root of 49, the positive value is obtained by finding the number that, when multiplied by itself, equals 49. By following this principle, we find that the positive square root of 49 is 7, represented as √49 = 7.
Negative Square Root: Discussing the negative value of the square root of 49, which is -7
While the positive square root of 49 is 7, it is important to note that there is also a negative square root. The negative square root is obtained by taking the negative value of the positive square root. Therefore, the negative square root of 49 is -7, denoted as -√49 = -7.
Multiplicative Inverse: Demonstrating that the positive and negative square roots of 49 are multiplicative inverses of each other
One interesting property of the square roots of any number is that the positive and negative square roots are multiplicative inverses of each other. In the case of 49, the positive square root, 7, and the negative square root, -7, are multiplicative inverses. This means that when these two values are multiplied together, the result is always 1. Thus, 7 multiplied by -7 is equal to -49, or (-7)(7) = -49.
