Integer or simplified fraction:)! help pls<3

Step-by-step explanation:

The question relates to the evaluation of an expression given the values of the variables of the expression;

The given expression is

The values of the terms at which the given expression is to be evaluated are;

f = -4 and j = 2

By plugging in the values, we get;

At f = -4 and j = 2,  

(-4)⁰ = 1

2⁻³ = 1/8

We get;

Therefore;

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
