I am looking for P in this equation in Matlab

I am looking for solving this equation into matlab and find P. I want to solve and find P as other parameters.

I edited my variable. In second attachment shows all parameters.

What should I do if I want to show the P answer as a parameter form?

Hopefully this will help @Pooya Jahedi too.

clear,clc

alpha = 0.5;
kH    = 1;
P0    = 1;
qm    = 2;
kS    = 0.01;
n     = 4;
qx    = 1;
func  = @(x) qx-(exp(-alpha*x)*kH*x+(1-exp(-alpha*x))*qm*(kS*x)^(1/n)/(1+(kS*x)^(1/n)));

P = P0*fzero(func,1)

P = 1.5681

Thank you for your answering to my question.

P cannot be expressed in parameter form - only a numerical solution with given values for the other parameters is possible.
