The equation xx=10100 may be rewritten as exp(ln(x))*ln(x) = 100*ln(10).
Lambert's W function is a function which satisfies the equation exp(W(x))*W(x) = x. That is, W is the inverse of f(x)=exp(x)*x. This function is mentioned in the FAQ for sci.math
Using this function, we get ln(x)=W(100*ln(10)), thus
