Let r = 1 + 2i and s = 3 + 3i. Find r*s.

r×s= -3+9i

Step-by-step explanation:

hello :

Let r = 1 + 2i and s = 3 + 3i.

r×s=(1+2i)(3+3i)=3+3i+6i+6i²   but : i²=-1

r×s= -3+9i

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
