Find the product of -2+2i and its conjugate

8

Step-by-step explanation:

The conjugate of - 2 + 2i is - 2 - 2i, hence

(- 2 + 2i)(- 2 - 2i) ← expand factors using FOIL

= 4 + 4i - 4i - 4i² [ note i² = - 1 ]

=  4 + 4

= 8

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.

hope my answer has you!

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
