How to write this equation into code?

I currently have it in this form and I am getting a weird answer:

    eqn3 = ((Ac*Pul)/(alpha*CF*miu))*((((Rm*Ac)/(alpha*CF))^2)+(((2*Ac)/(alpha*CF))*((Rm*Vcf)+((alpha*CF*(Vcf^2))/(2*Ac))+((Ac*Pul*(t-tcf))/miu))))^-(1/2) == Vt2;

When you have such a complex equation......it is confusing to type whole equation at once......try to type term by term and then see the answer.

T1 = Ac*Pul/(alpha*CF*mu) ;
T2 = (Rm*Ac/(alpha*CF))^2 ;
T3 = (2*Ac/(alpha*CF))*(Rm*VCF+(alpha*VCF^2)/(2*Ac)+(Ac*Pul*(t-tCF)/mu)) ;

J = T1*(T2+T3)^(-1/2) ;

Thank you for your input. I tried this and it did not work. It is still giving me a strange answer. Would you like me to give you the values of the constants?

We can't do much else until you do. The formula looks correct. Give values for all the variable, and your expected answer that is known to be correct.

the equation is set equal to Vt2, and I am solving for the variable 't'. The expected value of t is 2925.24, but I am getting 725764499.359.

CF = 4.5; % kg/m^3
Ac = 0.0018; % m^2
Vt1 = (1e-5)/60; % m^3/s
P0 = 2068.43; % Pa
Pul = 172368.93233; % Pa
miu = 1e-3; % Pa?s
alpha = 3.8e12; % m/kg
Rm = 22339043999.99; % m^-1
tcf = 1161.628; % s
Vcf = 0.0001936; % m^3
Vt2 = 8.333e-08; % m^3
