Find the missing term. () + (7 − 3i) + (5 + 9i) + 13i = 10 − 5i.

the missing term is

Step-by-step explanation:

Let

------> the missing term

we have

Combine like terms in the left side

Solve the system of equations

------> equation A

------> equation B

the missing term is

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

stop cheating
