Answer:
A
Step-by-step explanation:
Using the rule of radicals
[tex]\frac{\sqrt{a} }{\sqrt{b} }[/tex] = [tex]\sqrt{\frac{a}{b} }[/tex]
Given
[tex]\frac{\sqrt{80} }{\sqrt{5} }[/tex]
= [tex]\sqrt{\frac{80}{5} }[/tex] → I ( 80 ÷ 5 = 16, thus
= [tex]\sqrt{16}[/tex] → II ( and [tex]\sqrt{16}[/tex] = 4 ), thus
= 4 → III
