Question

Can someone help me please ASAP (Radical expressions)

Answer 1

A

Explanation:

Using the rule of radicals

`(√(a) )/(√(b) )` =
`\sqrt{(a)/(b) }`

Given

`(√(80) )/(√(5) )`

=
`\sqrt{(80)/(5) }` → I ( 80 ÷ 5 = 16, thus

=
`√(16)` → II ( and
`√(16)` = 4 ), thus

= 4 → III

Answer 2

A. I, II and III

Explanation:

`( √(80) )/( √(5) ) = \sqrt{ (80)/(5) } = √(16) = 4 \\`
