Thank you for the opportunity to help you with your question!
I have just solved the three equations with the help of my graphing calculator. i think I solved it right because my calculator is always right. So, I hope that helps. I have never solved equations like these, but the calculator helped me. It took me 10 minutes to solve this. I hope this helps.
1) x= -log(10) + 2i pi n/ log(2)
2) x= -log(3) +2i pi n/log(2)
3) x= -log(7) +2i pi n/log(2)
Please let me know if you need any clarification. I'm always happy to answer your questions.
