It looks like you've uploaded a math problem sheet. This sheet contains various equations that need to be solved, covering topics such as exponential equations, logarithms, and algebraic manipulations.

Would you like to go through the first question, or do you want help with a specific problem from the sheet? Let me know which part you'd like to focus on, and I'll help step by step.

If you want, I can also walk you through solving the first problem and then move on to others.
