Explicación paso a paso:
•7) (2/3)^-5=(3/2)^5.
•8) (2/3)^5.
•9) (2/3)^1=(2/3).
•10) [(3/2)^-2] : [(2/3)^-3] = [(2/3)^2] : [(2/3)^-3] = (2/3)^5.
•11) (2/3)^6.
•12) (2/3)^-24=(3/2)^24.
•13) [(4/9)^-2] : [(27/8)^-3] = [(9/4)^2] : [(8/27)^3] = [(9^2)×(27)^3] : [(4^2)×(8^3)] =
=[(3)^13] : [(2)^13] =(3/2)^13.
