Solve the following equation by writing expressions using positive indices. (picture attached)

-2

Step-by-step explanation:

[-2^(-3)]^(-3) =

(-1)^(-3) × [2^(-3)]^(-3)

= (-1) × 2^(+9) = -(2^9)

[2^(-2)]^(-4) = 2^(+8) = 2^8

-(2^9)÷(2^8)

-[2^(9-8)]

-2^(1) = -2

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
