Question

write three rational numbers between under root 3 and under root 2

Answer 1

$as \: \sqrt{3} = 1.732 \: and \\ \: \sqrt{2} = 1.414$
Therefore you have to find in between them which is greater than 1.414 and less than 1.732.
Their are many many rational numbers between them.
Eg- 1.4145
1.41422222...
1.41425
1.515151515.....
1.525
1.65
1.6666.....
These are some examples.
Just write numbers either terminates or recurring.

Answer 2

the rational numbers between under root 3 and root 2 is 1.72
