The square root of 28 is a mathematical operation that determines a number which, when multiplied by itself, equals 28. In other words, it finds the value that, when squared, gives the result of 28.
The answer to the square root of 28 is approximately 5.29.
The square root of 28 is an irrational number. An irrational number is a number that cannot be expressed as a fraction or a ratio of two integers. The decimal representation of the square root of 28 goes on indefinitely without repeating or terminating, indicating its irrationality.
There are several methods to solve for the square root of 28. Here, we will use the prime factorization method.
Step-by-step solution:
Example 1: To find the square root of 28, we can use the long division method. √28 = 5.29 (approximately)
Example 2: Using the estimation method, we can approximate the square root of 28 to the nearest whole number. √28 ≈ 5
Example 3: Using the Newton-Raphson method, we can iteratively approximate the square root of 28. Starting with an initial guess of x = 5, we can use the formula: x = (x + 28/x) / 2 After several iterations, we find that the square root of 28 is approximately 5.29.
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. It is denoted by the symbol √ and is used to find the side length of a square with a given area or to solve quadratic equations.
The square root of a number x can be calculated using the formula: √x = x^(1/2)
The symbol √ is used to represent the square root in mathematics.
There are two types of square roots: positive and negative. The positive square root is denoted by √x, while the negative square root is denoted by -√x. However, when we refer to the square root of a positive number, we usually mean the positive square root.
