Answer 2

Answer:

The answer is -491/4

Step-by-step explanation:

First divide the math into 3 parts based on the question.

part 1: +(128)^-1/4

part 2: -[(625)^-3]^-1/4

part 3: +14(2401)^-1/4

then solve the parts,

1.(128)^-1/4 = 1/4

2.[(625)^-3]^-1/4= -125

3.14(2401)^-1/4= 2

then add the following parts= 1/4-125+2

= -491/4
