(12)(√(a+(√(1+2)))) = 2            a+(√3)=4⇒a=4−(√3)  (13) (√(x+(√(2+2)))) =2             x+2=4⇒x=2
$$\left(\mathrm{12}\right)\sqrt{{a}+\sqrt{\mathrm{1}+\mathrm{2}}}\:=\:\mathrm{2} \\ $$$$\:\:\:\:\:\:\:\:\:\:{a}+\sqrt{\mathrm{3}}=\mathrm{4}\Rightarrow{a}=\mathrm{4}−\sqrt{\mathrm{3}} \\ $$$$\left(\mathrm{13}\right)\:\sqrt{{x}+\sqrt{\mathrm{2}+\mathrm{2}}}\:=\mathrm{2} \\ $$$$\:\:\:\:\:\:\:\:\:\:\:{x}+\mathrm{2}=\mathrm{4}\Rightarrow{x}=\mathrm{2} \\ $$
