Answer

Final Answer: The excluded value for the expression is $\boxed{10}$.

Steps

Step 1 ：The expression is undefined when the denominator equals zero. Therefore, we need to find the value of $v$ that makes $v-10=0$.

Step 2 ：Solving for $v$ in the equation $v-10=0$ gives us $v=10$.

Step 3 ：Final Answer: The excluded value for the expression is $\boxed{10}$.
