Answer 1

yes

Explanation:

Answer 2

Hello,

5.2²=27.04
5.5²=30.25

So
5.2<√28<5.5 √28≈5,29
or
5.2<√29<5.5 √29≈5,39
or
5.2<√30<5.5 √30≈5,48

But we may also use ∛

5.2³=140,608
5.5³=166,375

So
5.2<∛141<5.5 and ∛141=5,20482≈5.20
5.2<∛142<5.5 and ∛142=5,21710 ≈5.22
...
5.2<∛166<5.5 and ∛166=5,49586≈5.50
