f=@(h)h.^0.66+0.0805*h-0.045;
fzero(f,0.008);%plot(0:.001:.1,f(0:.001:.1)) to get approximate location to root

Probably the easiest approach:
syms h z2
Eqn = h^0.66+0.0805*h == 0.045;
[h,prms,cndx] = solve(Eqn,h, 'ReturnConditions',1)
vpa_cndx = vpasolve(z2^50 + (2000*z2^33)/161 - 90/161 == 0); % Returns All 50 Roots
.
