Question 415885
<font face="Times New Roman" size="+2">


Exponential?  Do you mean it is the index of the radical, like this:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt[\small{3}\LARGE]{x\ -\ 5}\ =\ 3\ \ ?]


Going on that presumption, raise each side of the equation to the third power.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ -\ 5\ =\ 27]


Solve for *[tex \Large x]


By the way, if I guessed right at what you were trying to render, there are two ways to do it in plain text:


1.  root(3,x - 5)


2.  sqrt[3](x - 5)

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