Explicación paso a paso:
Las potencias son una manera abreviada de escribir una multiplicación formada por varios números iguales.
a)
(2/3)² = (2/3) . (2/3) = 4/9
b)
(1/2)³ = (1/2) . (1/2) . (1/2) = 1/8
c)
(-2/3)² = (-2/3) . (-2/3) = 4/9
d)
(-1/2)³ = (-1/2) . (-1/2) . (-1/2) = -1/8
e)
(-2/5)⁻² = (-5/2)² = (-5/2) . (-5/2) = 25/4
f)
(-1/25)⁰ = 1
g)
(4)⁻² = (1/4)² = (1/4) . (1/4) = 1/16
h)
(-2)⁻³ = (1/-2)³ = 1/(-2)³ = 1/-8
