Question

Divide and write answer in standard complex form ( a + bi) 10+20i/4+2i

Answer 1

`4+3i`

Explanation:

=
`((10+20i))/(4+2i) \\\\(10+20 i)/(4+2i)`x
`((4-2i))/((4-2i))`

=
`((10+20i)(4-2i))/((4^(2)-2i^(2)) ) \\(40-20i+80i+40)/(16+4)\\ (80+60i)/(20)\\ 4+3i`(Taking 20 common from both numerator and deniminator)
