Problem Statement

In a Martian civilization, all logarithms whose bases are not specified are assumed to be base bb, for some fixed b2b \geq 2. A Martian student writes down \begin{align*}3 \log(\sqrt{x}\log x) &= 56\\\log_{\log (x)}(x) &= 54 \end{align*} and finds that this system of equations has a single real number solution x>1x > 1. Find bb.
