Step-by-step explanation:

We want to simplify the expression:

Rewrite:

Rewrite:

Simplify. Let i = √(-1). Hence:

Multiply:

In conclusion, our answer is C.

where are the images of the functions i can only see the question you typed.

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
