Match the products of complex numbers with their standard forms. (5-2i)(4-i) (2-5i)(1-4i) (1-4i)(5-2i) (4+i)(2-5i)

( 5 - 2i ) ( 4 - i )       18 - 13i

( 2 - 5i ) ( 1 - 4i )     -18 - 13i

( 1 - 4i ) ( 5 - 2i )      -3 - 22i

( 4 + i ) ( 2 - 5i )     13 - 18i

Step-by-step explanation:

Given : Complex numbers

1) (5-2i)(4-i)

2) (2-5i)(1-4i)

3) (1-4i)(5-2i)

4) (4+i)(2-5i)

To find : The products of complex numbers with their standard forms.  

Solution :

We simply apply multiplicative property of brackets,

i.e,

Note -

1) (5-2i)(4-i)

2) (2-5i)(1-4i)

3) (1-4i)(5-2i)

4) (4+i)(2-5i)  

Therefore, following above are the required results.

is means division by fractions
