I need to find the root of the following equation in matlab. Can can anyone help me to find the z values.
root(z^8 + (10548593400*z^6)/42679 + (33343133111071335000*z^4)/1821497041 + (211014867341025000000*z^2)/554827 - 142793543857500000000000000/10778089, z, 1)

You can get an analytical solution if you substitute y = z^2:
syms y
p = y^4 + (10548593400*y^3)/42679 + (33343133111071335000*y^2)/1821497041 + (211014867341025000000*y)/554827 - 142793543857500000000000000/10778089;
ysol = solve(p,y,'MaxDegree',4);
zsol = [sqrt(ysol),-sqrt(ysol)];
double(zsol)
syms z
sol = roots(sym2poly(z^8 + (10548593400*z^6)/42679 + (33343133111071335000*z^4)/1821497041 + (211014867341025000000*z^2)/554827 - 142793543857500000000000000/10778089))
