Step-by-step explanation:
An operation of two real numbers is defined by the rule

Calculate
First evaluate the expression in brackets:

Now,

Answer:
Mid-point: 
Equation: 
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.



To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB:
=
=
= 
Multiplying slopes that are perpendicular with each other always results in -1.


By the point slope form:

Plug in the coordinates of the mid-point:

Equation: 
Any log function/equation could be transformed in an exponential one:
log₂(x) = 4
x= 2⁴ and x = 16
