__Exercise 1__

Solve the equation
:

**The equations
below this point are of the form **
**and belong to a category of equations
known as inverse equations.**

__Example 4__

Solve the equation:

__Solution__

I observe that ,
since for x = 0 the equation becomes 1=0, which is not true.

I divide the equation (4) with
and we get :

But, according to the known formula we
can conclude the following:

.

Thus, equation (5) becomes:

Now let's say that .
The above equation becomes:
