I'm not sure about this problem, but I think the answer is -3/4i-3/4. Could anyone help me please?

**Damon**, Thursday, December 8, 2011 at 4:30amI guess you mean:

(3-3i)/4i

or

(3/4)(1/i -i/i)

so the real questions are:

What is 1/i and what is i/i

first one:

1/i * i/i = i/-1 = -i

second one:

i/i = 1

so we have:

(3/4)(-i - 1)

or

-3/4 - (3/4)i

so I agree except for the trivial point that that standard form is a + b i not b i + a
