A googolplex is defined as 10 raised to the power of a googol, which is (10^{10^{100}}). To determine the number of digits in a googolplex, you can use the formula for the number of digits in a number (n), which is given by ( \lfloor \log_{10}(n) \rfloor + 1). Applying this to a googolplex, it has (10^{100} + 1) digits. Thus, a googolplex has (10^{100}) digits, plus one additional digit.
