Question

How do you order the following from least to greatest `sqrt4, 1.8, -sqrt10, -sqrt(36/9), 5`?

Answer 1

Convert each radical into decimal form so they can be compared to the other numbers.

Explanation:

`sqrt(4)=2`
`-sqrt(10)~~-3.162`
`-sqrt(36/9)=-sqrt(4)=-2`

The numbers, in order, are:

`-sqrt10, -sqrt36/9, 1.8, sqrt4, 5`
