7) 1

8) $5^{m-n}$

9) $\frac{1}{2^{6} }$

10) $\frac{1}{2^{3} }$

Solve the following

Steps are in the attached image. My paper is ugly and looks crumbled because I was using a used paper, so don't mind it. Please make sure you learn how to find the answer. The most important part in Algebra is learning its rules and understanding how to apply it in each Q. The first ten Questions, however, don't require steps since it's one marks each but I hope you check out how to do it since Math is something which you don't byheart. I don't know the answer of 6th, cause it's confusing else the Q isn't complete. Hope it helps you, buddy. :)
