One thing to note is that, in googology, googolquadriplex is used more often to refer to your  googolplexianiteron, which I assume is 1010 10 googolplex , in which case (10100(4)10100) wouldn't be equal to googolquadriplex. (hint: (10100(1)10100) = (10100)10 100 = 10100*10 100 = 1010 2*10100 = 1010 2+100 = 1010 102 ≠ 1010 100 = googolplex)
