Factor your radicand:  *[tex \LARGE 98x^6\ =\ 2\,\cdot\,7\,\cdot\,7\,\cdot\,x^3\,\cdot\,x^3]


So


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{98x^6}\ =\ \sqrt{ 2\,\cdot\,7\,\cdot\,7\,\cdot\,x^3\,\cdot\,x^3}]


Take one of any factor that occurs in a pair out of the radical and eliminate the pair from under the radical.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \sqrt{98x^6}\ =\ 7x^3\sqrt{2}]

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