Simplify the expression: (3 − 4i) + (7 − 6i). 4 − 2i 4 − 10i 13 − 2i 10 − 10i
yulyashka [42]

Equivalent expressions are expressions of equal values

The simplified expression of (3 - 4i) + (7 - 6i) is 10- 10i

The expression is given as:

(3 - 4i) + (7 - 6i)

Remove brackets in the above expression

3 - 4i + 7 - 6i

Rewrite the expression by collecting the like terms

3 + 7- 4i  - 6i

Next, evaluate the like terms

10- 10i

Hence, the simplified expression of (3 - 4i) + (7 - 6i) is 10- 10i
