Answer:
![18\sqrt2](https://tex.z-dn.net/?f=18%5Csqrt2)
Step-by-step explanation:
To simplify:
![2 \sqrt{18}+ 3 \sqrt2+ \sqrt{162 }](https://tex.z-dn.net/?f=2%20%5Csqrt%7B18%7D%2B%203%20%5Csqrt2%2B%20%5Csqrt%7B162%20%7D)
First of all, let us write 18 and 162 as product of prime factors:
![18 = 2 \times \underline{3 \times 3}\\162 = 2 \times \underline{3 \times 3} \times \underline{3 \times 3}](https://tex.z-dn.net/?f=18%20%3D%202%20%5Ctimes%20%5Cunderline%7B3%20%5Ctimes%203%7D%5C%5C162%20%3D%202%20%5Ctimes%20%5Cunderline%7B3%20%5Ctimes%203%7D%20%5Ctimes%20%5Cunderline%7B3%20%5Ctimes%203%7D)
The pairs are underlined as above.
While taking roots, only one of the numbers from the pairs will be chosen.
Now, taking square roots.
![\sqrt{18} =3 \sqrt2](https://tex.z-dn.net/?f=%5Csqrt%7B18%7D%20%3D3%20%5Csqrt2)
![162 = 3 \times 3 \times \sqrt 2 = 9 \sqrt2](https://tex.z-dn.net/?f=162%20%3D%203%20%5Ctimes%203%20%5Ctimes%20%5Csqrt%202%20%20%3D%209%20%5Csqrt2)
So, the given expression becomes:
So, the answer is:
or 18 StartRoot 2 EndRoot
