The mathematical expression in the image is:

$\sqrt{1 + \frac{\sqrt{3}}{2}}$

Steps to Simplify:

1. First, simplify the expression under the square root: $1 + \frac{\sqrt{3}}{2}$.
2. Combine $1$ and $\frac{\sqrt{3}}{2}$ into a single fraction: $1 + \frac{\sqrt{3}}{2} = \frac{2}{2} + \frac{\sqrt{3}}{2} = \frac{2 + \sqrt{3}}{2}$
3. Now substitute this back into the original square root: $\sqrt{\frac{2 + \sqrt{3}}{2}}$
4. Finally, you can simplify this expression by recognizing that the square root of a fraction is the square root of the numerator divided by the square root of the denominator: $\frac{\sqrt{2 + \sqrt{3}}}{\sqrt{2}}$

This is the simplified form of the expression.
