Question

Can someone help me simplify this- step by step
-5+i/2i

Answer 1

HI!!

Answer 2

Multiply times the conjunct of the denominator:

the conjunct of an imaginary number a + bi
is a - bi

so we have -2i as the conjunct

10 i - 2i^2 / -4i^2

i^2 = 1

10i - 2

Answer 3

So 10i-2 is correct? I was kind of thinking it was 1/2+5i/2

Answer 4

Answer 5

Sorry, You're totally correct.

i = sqrt(-1)
i^2 = -1


-5 + i /2i

-2i ( -5 + i) / -4i^2

10i - 2i^2 / -4i^2

10i + 2/ 4

1/2 + 5i/2

I repeat my excuse, maybe I rushed a bit.
