Question

Write the greatest integer smaller than 2√5 and the smaller integer greater than 2√5?

Answer 1

☆You need to say what kind of number you are referring to, and to how many decimal places. If you're looking for the greatest whole number and/or integer, use a calculator to get the value of 2 root 5, which is 4.47. The greatest number smaller than that would be 4 and the smallest number greater than that would be 5. If you need decimals to the tenths or hundredths or thousandths, or ten thousandths, etc, you can find that too, just by carrying out the 2 root 5 to 4.472135955 and finding the number just below and just above that in each decimal place. 

OR

☆2√5 = 2 x 2.236 = 4.472 
So the greatest number smaller than 2√5 is 4 and the smallest number greater than 2√5 is 5. 
If you are not talking about whole numbers then there are infinitely many numbers and the answer is not unique.
