Wrong !!!  (√(12)) + (√(18)) → (√(12)) + (√(16))

$$\boldsymbol{{Wrong}}\:!!! \\ $$$$\sqrt{\mathrm{12}}\:+\:\cancel{\sqrt{\mathrm{18}}}\:\rightarrow\:\sqrt{\mathrm{12}}\:+\:\sqrt{\mathrm{16}} \\ $$

 (1/( (√4)+(√8))) +(1/( (√8)+(√(12))))+(1/( (√(12))+(√(16))))+...+(1/( (√(396))+(√(400)))) = T  T= (((√8)−(√4))/4)+(((√(12))−(√8))/4)+(((√(16))−(√(12)))/4)+...+(((√(400))−(√(396)))/4)  T=(1/4)((√(400))−(√4))=((20−2)/4)=4.5

$$\:\frac{\mathrm{1}}{\:\sqrt{\mathrm{4}}+\sqrt{\mathrm{8}}}\:+\frac{\mathrm{1}}{\:\sqrt{\mathrm{8}}+\sqrt{\mathrm{12}}}+\frac{\mathrm{1}}{\:\sqrt{\mathrm{12}}+\sqrt{\mathrm{16}}}+...+\frac{\mathrm{1}}{\:\sqrt{\mathrm{396}}+\sqrt{\mathrm{400}}}\:=\:{T} \\ $$$${T}=\:\frac{\sqrt{\mathrm{8}}−\sqrt{\mathrm{4}}}{\mathrm{4}}+\frac{\sqrt{\mathrm{12}}−\sqrt{\mathrm{8}}}{\mathrm{4}}+\frac{\sqrt{\mathrm{16}}−\sqrt{\mathrm{12}}}{\mathrm{4}}+...+\frac{\sqrt{\mathrm{400}}−\sqrt{\mathrm{396}}}{\mathrm{4}} \\ $$$${T}=\frac{\mathrm{1}}{\mathrm{4}}\left(\sqrt{\mathrm{400}}−\sqrt{\mathrm{4}}\right)=\frac{\mathrm{20}−\mathrm{2}}{\mathrm{4}}=\mathrm{4}.\mathrm{5} \\ $$$$ \\ $$
