What irrational number is between 4.47 and 4.48?

shepuryov [24]

Answer: √20 is between 4.47 and 4.48

Step-by-step explanation: Square roots of numbers between perfect squares are irrational numbers. 16 and 25 are squares of 4 and 5, so the irrational number we are looking for must be about halfway between 16 and 25.

$\sqrt{20} =4.472135955$ is more than 4.47 and less than 4.48
