From the image, I can identify that you are working on a complex mathematical expression involving fractions, square roots, and multiple terms. Here's a breakdown of the expression that I see:

The main part of the equation appears to involve a large square root over an expression involving several nested terms. Here is what I interpret:

\sqrt{\frac{5}{2} - \left( \frac{5}{3} \cdot \frac{5+1}{2} \cdot \frac{1}{3} - \frac{1}{2} \right)} \times \left( \frac{4+1}{3} \cdot \frac{2}{4} \right)}

Would you like me to go step-by-step through this expression and solve it for you?
