Question Number 140556 by mathsuji last updated on 09/May/21
if, m>0, then determine all real  numbers z which satisfy  z^2 ∙(m^((√z)−z)  − 1)−(√z)+1=0
$${if},\:{m}>\mathrm{0},\:{then}\:{determine}\:{all}\:{real} \\ $$$${numbers}\:\boldsymbol{{z}}\:{which}\:{satisfy} \\ $$$$\boldsymbol{{z}}^{\mathrm{2}} \centerdot\left({m}^{\sqrt{\boldsymbol{{z}}}−\boldsymbol{{z}}} \:−\:\mathrm{1}\right)−\sqrt{\boldsymbol{{z}}}+\mathrm{1}=\mathrm{0} \\ $$

z≥t_0 ^2  with t_0  being the positive root of t^4 +t−1=0  t_0 ≈.724491959001 ⇒ t_0 ^2 ≈.524888599  0≤m<1 ∀ z≥t_0 ^2
$${z}\geqslant{t}_{\mathrm{0}} ^{\mathrm{2}} \:\mathrm{with}\:{t}_{\mathrm{0}} \:\mathrm{being}\:\mathrm{the}\:\mathrm{positive}\:\mathrm{root}\:\mathrm{of}\:{t}^{\mathrm{4}} +{t}−\mathrm{1}=\mathrm{0} \\ $$$${t}_{\mathrm{0}} \approx.\mathrm{724491959001}\:\Rightarrow\:{t}_{\mathrm{0}} ^{\mathrm{2}} \approx.\mathrm{524888599} \\ $$$$\mathrm{0}\leqslant{m}<\mathrm{1}\:\forall\:{z}\geqslant{t}_{\mathrm{0}} ^{\mathrm{2}} \\ $$
