2. How did you get s^2? And how did the denominator become 2?

3. 5/10 = 1/2

subtract exponents when dividing

s^-7 / s^-9 = s^-7 * s^9 = s^2

Looks like you need to review dividing powers. Also constructing fractions.

4. Got it now.

BTW, I started learning how to divide powers less than 30 minutes ago, so I'm not going to revise, yet :).
