multiply it by (2+i)/(2+i) this will rationalize the denominator so it is simplified

Answer 2

post what u get, then ill tell u what to do

Answer 3

1+5i ?

but..did u mean by multiply it's conjugate?

Answer 4

yes conjugate sorry, so multiply it by (2-i)/(2-i)

Answer 5

then, what should the next step be?

Answer 6

let me know if u have trouble understanding that

Answer 7
