To start, let's define what a square root is. A square root is a number that when multiplied by itself, gives the original number. In other words, the square root of 45 is a number that when multiplied by itself, equals 45. This number is represented by the symbol √45.

Now, you might be wondering how to simplify the square root of 45. To do this, we need to factorize 45. We can break down 45 into its prime factors, which are 3, 3, and 5. Therefore, we can write the square root of 45 as √(3 x 3 x 5).

Next, we can simplify this expression by taking out any pairs of numbers that are multiplied together. In this case, we have two 3s that can be multiplied together to get 9. So, we can rewrite √(3 x 3 x 5) as √(9 x 5).

Now, we can take the square root of 9, which is 3, and leave the square root of 5 under the radical sign. Thus, the simplified form of the square root of 45 is 3√5.

But why do we need to simplify the square root of 45? Well, simplifying radicals makes them easier to work with in equations and calculations. It also allows us to compare and order different square roots more easily.

Another question you might have is how to approximate the value of the square root of 45. While the exact value of the square root of 45 is 3√5, we can estimate its decimal value by using a calculator or long division.

For example, if we use long division, we can start by guessing that the square root of 45 is between 6 and 7. We then divide 45 by 6, which gives us 7.5. Next, we average 6 and 7 to get 6.5, and divide 45 by 6.5, which gives us 6.92307692. We can continue this process until we get as many decimal places as we need.

In conclusion, the square root of 45 simplified is 3√5. This expression can be written in different forms depending on the context, but simplifying it makes it easier to work with and compare. Whether you're a math whiz or just starting to explore the world of numbers, understanding square roots and their properties is an essential part of mathematical literacy.
