Question

Subject to some of (3/5 + 1/5i) and (4/5 - 2/5i) from (9/5 - 1/5i). the result is what

Answer 1

Result = 2/5

Step-by-step explanation:

Question: Subtract to sum of (3/5 + 1/5i) and (4/5 - 2/5i) from (9/5 - 1/5i).

First we will take sum of (3/5 + 1/5i) and (4/5 - 2/5i):

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

= 3/5 + 1/5i + 4/5 - 2/5i

= 3/5 + 4/5) + (1/5i - 2/5i)

= (7/5 - 1/5i)

Now subtract (7/5 - 1/5i) from (9/5 - 1/5i).

(9/5 - 1/5i) - (7/5 - 1/5i)

= 9/5 - 1/5i - 7/5 -1/5i

= (9/5 - 7/5) - (1/5i + 1/5i)

= (2/5) - 0

= 2/5

Result = 2/5

Answer 2

The correct answer is: 2/5.

Step-by-step explanation:

First you have to add the following expressions:

`((3)/(5)+(1)/(5)i)+((4)/(5)-(2)/(5)i) \\ ((3)/(5)+ (4)/(5))+((1)/(5)i-(2)/(5)i) \\= (7)/(5)-(1)/(5)i`

Now subtract the above expression from
`((9)/(5)-(1)/(5)i)`:

`((9)/(5)- (1)/(5)i) - ((7)/(5) -(1)/(5)i) \\ ((9)/(5) -(7)/(5)) + ((1)/(5)i -(1)/(5)i) \\ (2)/(5) \\`

Hence the correct answer is 2/5.
