Problem 7

Explanation

Based on the definition of the operation $\odot$, we will calculate the value of $(5 \odot 2) \odot 3$ step by step. First, we calculate the part inside the parentheses, which is $5 \odot 2$ with $a = 5$ and $b = 2$.

Next, we operate the result with $3$. Now we calculate $24 \odot 3$ with $a = 24$ and $b = 3$.

Thus, the value of $(5 \odot 2) \odot 3$ is $208$.
