Step 1 There is a relationship between H and a. So it called a formula to get the value of H for different values of a. The process of finding such equations to describe real-world phenomena is called mathematical modeling. Step 2 Such equations, together with the meaning assigned to the variables, are called mathematical models.

Solving equations of type x 1 / n = log n x
First, I'm a new person on this site, so please correct me if I'm asking the question in a wrong way.
I thought I'm not a big fan of maths, but recently I've stumbled upon one interesting fact, which I'm trying to find an explanation for. I've noticed that graphs of functions y = x 1 / n and y = log n x , where n is given and equal for both functions, always have 2 intersection points. This means, equation x 1 / n = log n x must have 2 solutions, at least it's what I see from the graphs.
I've tried to solve this equation analytically for some given n, like 4, but my skills are very rusty, and I cannot come up with anything. So I'm here for help, and my question(-s) are:
are these 2 functions always have 2 intersection points?
if yes, why, if not, when not?
how to solve equations like x 1 / n = log n x analytically?
