Show an example of a rational number that is between √10 and √11

1 answer

One rational number that is between √10 and √11 is 3.2.

To show that 3.2 is rational and lies between √10 and √11, we can square both numbers:

(√10)^2 = 10
(√11)^2 = 11

So, we know that √10 < 3.2 < √11.

To demonstrate that 3.2 is rational, we can express it as a fraction by finding the quotient of two integers:

3.2 = 32/10 = 16/5

Therefore, 3.2 is a rational number between √10 and √11.
