The image contains an expression that seems to involve square roots. Here's what I can see from the image:

$\sqrt{48} + \sqrt{108} - \sqrt{27}$

Let me simplify this expression step by step:

1. Simplifying the square roots:

$\sqrt{48} = \sqrt{16 \times 3} = 4\sqrt{3}$ $\sqrt{108} = \sqrt{36 \times 3} = 6\sqrt{3}$ $\sqrt{27} = \sqrt{9 \times 3} = 3\sqrt{3}$

2. Substituting the simplified values:

$4\sqrt{3} + 6\sqrt{3} - 3\sqrt{3}$

3. Combining the terms:

$(4 + 6 - 3)\sqrt{3} = 7\sqrt{3}$

So, the simplified form of the expression is: $7\sqrt{3}$
