Question #961d9

Answer 1

`8`

Explanation:

We can write the expressions in the brackets as they are since they are being multiplied by 1, and collect like terms.

`rArr(color(blue)(3)color(red)(+2i))+(color(blue)(5)color(red)(-2i))`

`=color(blue)(3)color(red)(+2i)+color(blue)(5)color(red)(-2i)`

`=8`
