nonlinear equations

[moujail]

Hi everybody,

I am a biginner in Matlab (Release 13)
I have to resolve the following non linear systems of equations:

5.387=k1+k2+k3+3.92
0.022=sqrt{5.387-4*[k3*(3.92+k2)+k1*(k2+k3)]}
1.51326= {3.92+k1+k2+k4+sqrt[(3.92+k1+k2+k4)^2-4*k1*(k2+k4)]}/2
1.52376={3.92+k1+k2+k4-sqrt[(3.92+k1+k2+k4)^2-4*k1*(k2+k4)]}/2

May somebody help me???
Thanks

Define what Chemical application this is for and give the bounds on the k's. Put the equations in a more standard form and look at help in MATLAB for the nonlinear solutions. If this is for school, there should be some help files in the course notes.
