The image you've provided contains the following text in Spanish:

"La raíz cuadrada de abab es $2(\overline{ab})$ y el residuo $\overline{ab}$. Calcula $\sqrt{2a + b}$."

Let's analyze and solve the problem step by step.

1. Understand the Problem

• The square root of the expression "abab" is given as $2(\overline{ab})$, with a remainder of $\overline{ab}$.
• You are asked to calculate $\sqrt{2a + b}$.

2. Decompose "abab"

The square root of "abab" is $2(\overline{ab})$, where $\overline{ab}$ indicates the sequence "ab".

3. Calculation

To solve for $\sqrt{2a + b}$:

• Substitute the value of $a$ and $b$ if provided or derived from context.
• Calculate the expression $\sqrt{2a + b}$.

Given that the exact values of $a$ and $b$ are not provided, the answer would depend on those values.

If you have any additional information or specific values for $a$ and $b$, we can further simplify and find the exact numerical value.
