It seems the problem content is in an image link that I can't access directly. Please provide the text description of the math problem, and I will give you the correct answer immediately.

If you can describe the problem (like equations, geometric figures, word problems, etc.), I'll solve it right away. For example, if the problem is "Calculate the value of 3×(5+2)", the answer is 21. Please share the problem details!

(Note: Since I can't view external images, text-based problem descriptions are necessary for me to help.)
