Answer:
4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
To simplify , multiply the numerator/ denominator by [tex]\sqrt{5}[/tex]
[tex]\frac{20(\sqrt{5}) }{\sqrt{5}(\sqrt{5}) }[/tex]
= [tex]\frac{20\sqrt{5} }{5}[/tex]
= 4[tex]\sqrt{5}[/tex]
[tex]4\sqrt5x}[/tex]
[tex]\frac{20}{\sqrt{5} }[/tex] multiplied by [tex]\frac{\sqrt{5} }{\sqrt{5} }[/tex]
Then, simplify:
[tex]\frac{20 \sqrt{5} }{\sqrt{5} }[/tex]
[tex]4\sqrt{5}[/tex]
