Answer 1

Respuesta:

Explicación paso a paso:

1)

a) (-3/5)^4 = (-3)^4/(5)^4 = 81/625

b)  (9/16)^(1/2) = (9)^(1/2)/(16)^(1/2) = 3/4

c) (8/27)^(1/3) = (8)^(1/3)/(27)^(1/3) = 2/3

2)

a) 6^(2x^2+6x-8) = 1

2x^2+6x-8=0

(2x)^2+6(2x) -16 = 0

(2x + 8)(2x - 2) = 0

(x + 4) (x - 1) = 0

x= -4     x= 1
