8/(4-i) ?

OpenStudy (anonymous):

I'm guessing they want you to rationalize? 8/(4-i) 8(4+i) / (4-i)(4+i) Multiply by the conjugate on top and bottom. 8(4+i) / 16-i^2 8(4-i)/ 16-(-1) 8(4-i)/ 17

OpenStudy (anonymous):

Isn't it 8(4+i)/17? as you times the top part by (4+i)

OpenStudy (anonymous):

yeah so srry! typo!

OpenStudy (anonymous):

Ahaha yeah :)
