wrt. http://mathworld.wolfram.com/SixExponentialsTheorem.html and http://mathworld.wolfram.com/FourExponentialsConjecture.html what is known if x1,x2 are linearly independent complex numbers, as are y1,y2 and z1,z2. Then must one of; e^x1y1, e^x1y2, e^x2y1, e^x2y2, e^x1z1, e^x1z2, e^x2z1, e^x2z2, e^y1z1, e^y1z2, e^y2z1, e^y2z2 be transcendental?
