For instance, the square root of 9 is 3 because 3 x 3 = 9. Similarly, the square root of 16 is 4 because 4 x 4 = 16. The symbol used for square root is √, and the number under the symbol represents the radicand or the number being evaluated.

The Calculation of Square Root of 405

Now that we have a basic understanding of square roots, let us find out the square root of 405. We can calculate it in two ways: manually or using a calculator. However, let us first discuss the manual method.

The Manual Method

The manual method involves finding the factors of the number being evaluated and then simplifying it into perfect squares. Here are the steps to find the square root of 405 manually:

Write the number 405 as a product of its prime factors: 3 x 3 x 3 x 5 x 3.
Group the factors in pairs starting from the right: (3 x 3), (3 x 5), and 3.
Multiply each pair and write their products: 9, 15, and 3.
Add the products to get the sum: 9 + 15 + 3 = 27.
Take the square root of the perfect square factor: √9 = 3.
Write the answer: √405 = 3√15.

Hence, the square root of 405 is 3√15.

The Calculator Method

The calculator method is the quicker and easier way to find the square root of any number, including 405. All you need is a scientific calculator with a square root function. Here are the steps to find the square root of 405 using a calculator:

Turn on your calculator and press the number 405.
Press the square root button (√).
The answer will be displayed on the screen: 20.1246118.

Therefore, the square root of 405 is approximately 20.12 when rounded off to two decimal places.

Applications of Square Roots

Square roots have several practical applications in various fields, such as science, engineering, and finance. Here are some examples:

In Engineering

Square roots are used in engineering to calculate the length, width, and height of 3D objects. For example, the formula for the volume of a cube is V = a³, where V is the volume and a is the length of the sides. To find the length, we need to take the cube root of the volume: a = ∛V.

In Finance

Square roots are used in finance to calculate the standard deviation of a set of data, which is a measure of the amount of variation or dispersion in a dataset. The formula for standard deviation is σ = √((∑(x - μ)²)/n), where σ is the standard deviation, x is the data set, μ is the mean, and n is the number of data points.
