ANSWER
The first three expressions will simplify to a rational answer.
EXPLANATION
Let us simplify the expressions then we can see which of them are rational.
A.
![7\sqrt{3} \times \sqrt{3}](https://tex.z-dn.net/?f=7%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B3%7D)
We multiply out the roots to get
![7\sqrt{3} \times \sqrt{3}=7 \times (\sqrt{3})^2](https://tex.z-dn.net/?f=7%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B3%7D%3D7%20%5Ctimes%20%28%5Csqrt%7B3%7D%29%5E2)
This simplifies to
![7\sqrt{3} \times \sqrt{3}=7 \times 3](https://tex.z-dn.net/?f=7%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B3%7D%3D7%20%5Ctimes%203)
![7\sqrt{3} \times \sqrt{3}=21](https://tex.z-dn.net/?f=7%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B3%7D%3D21)
This is a rational number hence the answer is rational.
B.
![\sqrt{5} \times \sqrt{5}=(\sqrt{5})^2](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%20%5Ctimes%20%5Csqrt%7B5%7D%3D%28%5Csqrt%7B5%7D%29%5E2)
![\sqrt{5} \times \sqrt{5}=5](https://tex.z-dn.net/?f=%5Csqrt%7B5%7D%20%5Ctimes%20%5Csqrt%7B5%7D%3D5)
This is also a rational solution.
C.
![2\sqrt{9} \times \sqrt{4}=2\times3\times2](https://tex.z-dn.net/?f=2%5Csqrt%7B9%7D%20%5Ctimes%20%5Csqrt%7B4%7D%3D2%5Ctimes3%5Ctimes2)
![2\sqrt{9} \times \sqrt{4}=12](https://tex.z-dn.net/?f=2%5Csqrt%7B9%7D%20%5Ctimes%20%5Csqrt%7B4%7D%3D12)
This one too is a rational solution.
D.
![\sqrt{3} \times \sqrt{16}=\sqrt{3}\times4](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B16%7D%3D%5Csqrt%7B3%7D%5Ctimes4)
![\sqrt{3} \times \sqrt{16}=4\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20%5Ctimes%20%5Csqrt%7B16%7D%3D4%5Csqrt%7B3%7D)
This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.
