1. $\sqrt{100} \sqrt{100}$

2. 13.5 + $\sqrt{81}$

3. $\sqrt{9} + \sqrt{729}$

6. $\frac{3}{5} + 2.5</p<pThese four options are rational;</p <p<strongStep-by-step explanation:</strong</p<p1. [tex]\sqrt{100} \sqrt{100}$ equals to 10 * 10 = 100 which is rational

2. 13.5 + $\sqrt{81}$ equals 13.5 + 9 = 22.5

3. $\sqrt{9} + \sqrt{729}$ -- 3+27 = 30

6. $\frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1$

Option 4 and 5 are irrational because they include $\sqrt{353}$ and $\sqrt{216}$ which are not a perfect square and their answers will be non recurring and non terminating decimal fraction.
