1. -2^-5 = -1/32
--------------------------
2. (-2)^-4 = 1/16
--------------------------
3. (-4)^-3 = -1/64
--------------------------
4. (-1)^-5 = -1
--------------------------
5. (-6+3)^-3 = (-3)^(-3) = -1/27
----------------------------
6. (6*2)^-4 = 1/12^4 = 1/20,736
----------------------------
7. K^-3/r5 =1/(k^3*r^5)
------------------------------
8. Z^-4/5t^-2 = t^2/5z^4
---------------------------------
9. -3t^4/q^-5 = -3t^4*q^5
-----------------------------------
10. 3f^-1y^-5 = 3y^5/f
