I have to simplify this:

5/3sqrt(3-4)

I am not sure if you have to conjugate the denominator and multiply it with the top and bottom, then simplify from there or if the 3-4 equals -1 and you end up with i, an imaginary number in the radical. If so, I really do not understand what I would do from there. Please help!

**Reiny**, Tuesday, January 8, 2013 at 7:40pmSo your question is really:

5/(3√-1)

If you want to make the denominator real, or to "realize" the denominator, then ....

= 5/(3√-1) * (√-1/√-1)

= 5√-1/-3

= -5√-1/3 or -5i/3

Unless there were other imaginary numbers in the rest of your questions, I suspect a typo of sorts here.
