Answer 1

see explanation

Explanation:

(a)

to say
`√(32)` = 2
`√(16)`

is incorrect in that she has taken the 2 outside the radical, when

(b)

using the rule of radicals

`√(a)` ×
`√(b)` ⇔
`\sqrt{ab`

then

`√(32)`

=
`√(2(16))` ( note 2 remains inside the radical )

=
`√(2)` ×
`√(16)`

=
`√(2)` × 4

= 4
`√(2)`

≈ 4 × 1.5

= 6
