Square Root of 2209

Accepted Solution

Solution: The square root of 2209 is 47 Methods What is the Square Root of 2209? To start with, let’s review what we define as the square root of a number. A square root of a number is a number that when multiplied by itself gives the original value. So, for instance, the square root of 16 is 4 or √16 = 4, then by definition, we can also say that 4 • 4 is also 16. Now, for the Square Root of 2209, the value is 47. It is noteworthy that the result of a square root can be either a whole number or a decimal. Is the Square Root of 2209 rational? Oftentimes when it comes to square roots, it is helpful to know if the value of the square root is rational or irrational. A rational number is when you have a number that can be written as a fraction that divides two integers (as long as the denominator is not 0). Whole numbers can also be rational numbers! So, an irrational number would be a decimal that cannot be written as a fraction and is considered to go on and on with no end (non-terminating). In this case, because the square root of 2209, 47, is a whole number (and not a decimal), we say that 2209 is rational. How do you find the Square Root of 2209? There are two main ways to calculate the Square Root of a number: perfect squares and long division. Generally speaking, the first method that uses perfect squares is one of the easier and efficient methods when the number you have is a perfect square. To reiterate, a perfect square occurs when the value of the square root is a whole value. On the other hand, long division is used when the value of the square root is a decimal or not a perfect square. Our first attempt will be to try to see if we can use perfect squares. So, let's see if we can rewrite 2209 as a product of a number times itself. Well, we know the common perfect square of: 47 × 47 = 2209 47 × 47 = 2209 47 × 47 = 2209 Therefore: 2209 = 4 7 2 = 47 \sqrt{2209} = \sqrt{ 47^{2} } = 47 2209 ​ = 4 7 2 ​ = 47 Thus, helping us arrive at the conclusion that the Square Root of 2209 is 47.
