It is the biggest number. 10^∞.
10^(infinity*3)
Infinitillion is 10 to the power of, well… infinity. So it is basically just infinity. (This answer may not be correct)
Smallest: -infinitillion -10^∞. (or 0 in module) Biggest: infinitillion 10^∞.
No. Then comes quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, etc., etc. Numbers go on forever, so there is no biggest number. Infinity is not a number.
