Answer

$2; 2;$

Work Step by Step

We are given: $$\begin{cases} 1\text{ googol}&=10^{100}\\ 1\text{ googolplex}&=10^{googol}. \end{cases}$$ Calculate $\log(\log{(\text{googol})})$: $$\begin{align*} \log(\log{(\text{googol})})&=\log(\log 10^{100})\\ &=\log 100\\ &=\log 10^2\\ &=2. \end{align*}$$ Calculate $\log\log(\log{(\text{googolplex})}))$: $$\begin{align*} \log(\log(\log{(\text{googolplex})}))&=\log(\log(\log 10^{\text{googol}}))\\ &=\log (\log (\text{googol}))\\ &=2. \end{align*}$$
