Which of the following are examples of rational numbers? select all that apply. \sqrt{4} + \sqrt{16} \sqrt{5} + \sqrt{36} \sqrt{9} + \sqrt{24} 2 · \sqrt{4} \sqrt{49} · \sqrt{81} 3\sqrt{12}

Answer with Step-by-step explanation:

\sqrt{4} + \sqrt{16}

=2+4

=6 which is rational

\sqrt{5} + \sqrt{36}

=√5 +6  which is irrational

\sqrt{9} + \sqrt{24}

=3+4√6which is irrational

2 \sqrt{4}

=2×2

=4 which is rational

\sqrt{49} · \sqrt{81}

=7×9

=63 which is rational

3\sqrt{12}

=3×4√3

=12√3 which is irrational

Hence, example of rational numbers are:

\sqrt{4} + \sqrt{16}

2 · \sqrt{4}

\sqrt{49} · \sqrt{81}

it has the same slope and a different y-intercept

hope this : )
