Question 498520
<font face="Times New Roman" size="+2">


We don't do entire assignments here.  One question per post.  I'll give you a few facts to guide you though.


1.  The square root of any negative number is the imaginary number *[tex \Large i] times the square root of the positive of the number.  That is to say, for *[tex \Large a > 0], *[tex \Large \sqrt{-a}\ =\ i\sqrt{a}] where *[tex \Large i] is defined by *[tex \Large i^2\ =\ -1]


2.  The square root of a quotient is equal to the quotient of the square root of the numerator and the square root of the denominator.  That is to say: *[tex \Large \sqrt{\frac{a}{b}}\ =\ \frac{\sqrt{a}}{\sqrt{b}}]

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
