2√5 = 2 x 2.236 = 4.472

Finding the greatest integer smaller than 2√5 and the smallest integer greater than 2√5

To find the greatest integer smaller than 2√5 and the smallest integer greater than 2√5, we need to first understand what √5 is and how it relates to integers.

What is √5?
√5 is the square root of 5. It is an irrational number, which means it cannot be expressed as a fraction of two integers. Its decimal representation goes on forever without repeating.

How to find the greatest integer smaller than 2√5?
To find the greatest integer smaller than 2√5, we need to first calculate 2√5. We can use a calculator to do this or use the fact that √5 is approximately 2.236. Multiplying 2 and 2.236, we get 4.472. The greatest integer smaller than 4.472 is 4. Therefore, the greatest integer smaller than 2√5 is 4.

How to find the smallest integer greater than 2√5?
To find the smallest integer greater than 2√5, we need to add 1 to 2√5. Using the approximate value of √5 as 2.236, we can calculate 2√5 as 4.472. Adding 1 to this, we get 5.472. Therefore, the smallest integer greater than 2√5 is 6.

Conclusion
The greatest integer smaller than 2√5 is 4, and the smallest integer greater than 2√5 is 6.
