We conclude that:

Step-by-step explanation:

Given

Let the expression

To determine

Simplify the expression in only positive exponents

Simplifying the expression

Given the expression

Apply exponent rule:  

as 4³ = 64, so

Therefore, we conclude that:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
