$$
\sqrt{50} + \sqrt{18}
$$
#### Solution:
1. Simplify each square root:
- $\sqrt{50} = \sqrt{25 \cdot 2} = \sqrt{25} \cdot \sqrt{2} = 5\sqrt{2}$
- $\sqrt{18} = \sqrt{9 \cdot 2} = \sqrt{9} \cdot \sqrt{2} = 3\sqrt{2}$
2. Add the simplified terms:
$$
\sqrt{50} + \sqrt{18} = 5\sqrt{2} + 3\sqrt{2} = (5 + 3)\sqrt{2} = 8\sqrt{2}
$$
#### Final Answer:
$$
\boxed{8\sqrt{2}}

$$
\sqrt{72} - \sqrt{8}
$$
#### Solution:
1. Simplify each square root:
- $\sqrt{72} = \sqrt{36 \cdot 2} = \sqrt{36} \cdot \sqrt{2} = 6\sqrt{2}$
- $\sqrt{8} = \sqrt{4 \cdot 2} = \sqrt{4} \cdot \sqrt{2} = 2\sqrt{2}$
2. Subtract the simplified terms:
$$
\sqrt{72} - \sqrt{8} = 6\sqrt{2} - 2\sqrt{2} = (6 - 2)\sqrt{2} = 4\sqrt{2}
$$
#### Final Answer:
$$
\boxed{4\sqrt{2}}
$$

$$
\sqrt{27} - \sqrt{3}
$$
#### Solution:
1. Simplify each square root:
- $\sqrt{27} = \sqrt{9 \cdot 3} = \sqrt{9} \cdot \sqrt{3} = 3\sqrt{3}$
- $\sqrt{3}$ remains as it is.
2. Subtract the simplified terms:
$$
\sqrt{27} - \sqrt{3} = 3\sqrt{3} - \sqrt{3} = (3 - 1)\sqrt{3} = 2\sqrt{3}
