The expression in the image is:

$\sqrt{22 - 4\sqrt{30}}$

To simplify or evaluate this expression, we can try different methods, such as factoring or checking if there's a way to simplify the square root expressions. However, there doesn't appear to be an immediate simplification for this form using elementary methods, since both $\sqrt{22}$ and $\sqrt{30}$ are irrational and the expression $22 - 4\sqrt{30}$ doesn't simplify into a perfect square.

Would you like me to approximate the value of this expression numerically, or would you like further exploration into different methods of simplification?
