Question

\(\dfrac{5+\sqrt{5}}{\sqrt{5}}\)

Answer 1

\(\dfrac{5+\sqrt{5}}{\sqrt{5}}\)

\(=\dfrac{\sqrt{5}\cdot\sqrt{5}+\sqrt{5}}{\sqrt{5}}\)

\(=\dfrac{\sqrt{5}\cdot\sqrt{5}+\sqrt{5}\cdot1}{\sqrt{5}}\)

\(=\dfrac{\sqrt{5}\left(\sqrt{5}+1\right)}{\sqrt{5}}\)

\(=\sqrt{5}+1\)

Answer 2

giải từng bước giúp mình nhé

 

Answer 3

\(=\dfrac{\sqrt{5}\cdot\sqrt{5}+\sqrt{5}\cdot1}{\sqrt{5}}=\dfrac{\sqrt{5}\left(\sqrt{5}+1\right)}{\sqrt{5}}=\sqrt{5}+1\)
