Question

02.06 MC)Simplify the expression (3–21)+ (1+5i). (5 points)

Answer 1

The given expression is

`(3-21)+(1+5i)`

We just have to reduce like terms, first, we subtract the first two numbers

`-18+1+5i`

Then, we subtract again because 18 and 1 have different signs

`5i-17`

Hence, the simplified expression is 5i - 17.
