3^x −2^x =x^2 +10  find  (3^x −10)^2 (2^x −1)
$$\mathrm{3}^{{x}} −\mathrm{2}^{{x}} ={x}^{\mathrm{2}} +\mathrm{10} \\ $$$${find} \\ $$$$\left(\mathrm{3}^{{x}} −\mathrm{10}\right)^{\mathrm{2}} \left(\mathrm{2}^{{x}} −\mathrm{1}\right) \\ $$

Obviously x=3  27−8=9+10  ⇒  (27−10)^2 (8−1)=17^2 7=2023
$$\mathrm{Obviously}\:{x}=\mathrm{3} \\ $$$$\mathrm{27}−\mathrm{8}=\mathrm{9}+\mathrm{10} \\ $$$$\Rightarrow \\ $$$$\left(\mathrm{27}−\mathrm{10}\right)^{\mathrm{2}} \left(\mathrm{8}−\mathrm{1}\right)=\mathrm{17}^{\mathrm{2}} \mathrm{7}=\mathrm{2023} \\ $$
