The image you've uploaded appears to be a screenshot of a document containing mathematical equations. To assist you better, I'll first extract and analyze the mathematical content from the image and then provide the answers and explanations for the problems shown.

Let me process the image to extract the relevant mathematical details.It seems that the text in the image contains equations and steps related to the solution of a mathematical problem. However, the quality of the image makes it difficult to clearly extract all the details.

If you can upload a clearer version of the image or type out the specific problem you're asking about, I would be able to provide a more accurate and detailed solution. Alternatively, if you describe the type of problem it is (e.g., differentiation, integration, etc.), I could guide you through solving a similar problem.
