V100

Answer 1

Answer:

$the \: rational \: number \: is \: \sqrt{100}$

Step-by-step explanation:

The reason why

$\sqrt{97}$

isn't a rational number is because, when simplified, it results in 9.848857802.... its decimal doesn't terminate(stop).

The reason why

$\sqrt{98}$

isn't a rational number is because, when simplified, it results in 9.899494937.... it's decimal doesn't terminate(stop).

The reason why

$\sqrt{99}$

isn't a rational number is because, when simplified, it results in 9.949874371.... it's decimal doesn't terminate(stop).

The reason why

$\sqrt{100}$

is a rational number is because, when simplified, it results in 10, its decimal terminates (stops).

Answer 2

100 is rational because can be expressed as the quotient of two integers
