(2/5 x^-2)^-3 = (2/5)^-3(x^-2)^-3 = (5/2)^3(x^-2)-3
When you raise a power to a power, multpliy exponents:
so you get:
5^3/2^3(x^6) or A: (125/8)x^6

The convention for exponentiation is the use of the ^ between the number or variable and the exponent.
(2/5x^-2)^-3 = (125x6)/8

okey here's how u solve it:
(2/5 x - 2)-3
-4/5 x - 3
12/5
negative and negative will give u positive....so i think your answer is 12/5...
That's the answer!
