A fzgargoogolplex or fzgoogolduplex is equal to \( ext{googolduplex}^{ ext{googolduplex}}\). It evaluates to: \((10^{10^{10^{100}}})^{10^{10^{10^{100}}}} = 10^{10^{10^{10^{100}}} imes 10^{10^{100}}} = 10^{10^{10^{10^{100}}+10^{100}}}\). It is comparable to a googoltriplex, even though it's actually equal to raising a googoltriplex to the power of a googolplex. Both names for this number come from fz- plus names for 101010100.
