The equation has one extraneous solution which is n ≈ 2.38450287.
Given that,
The equation;

We have to find,
How many extraneous solutions does the equation?
According to the question,
An extraneous solution is a solution value of the variable in the equations, that is found by solving the given equation algebraically but it is not a solution of the given equation.
To solve the equation cross multiplication process is applied following all the steps given below.

The roots (zeros) are the  x  values where the graph intersects the x-axis. To find the roots (zeros), replace  y 
with  0  and solve for  x. The graph of the equation is attached.
n  ≈  2.38450287
Hence, The equation has one extraneous solution which is n   ≈  2.38450287
