Question

How do you order the following from least to greatest `4.8, sqrt17, -sqrt8, -4.2, sqrt25`?

Answer 1

Square the numbers (not the negative signs) then place them in order.

Explanation:

`4.8^2` = 23.04,
`(sqrt17)^2` = 17,
- `(sqrt8)^2` = - 8,
- `4.2^2` = - 17.64,
`(sqrt25)^2` = 25, now order them least to greatest:
- 17.64, - 8, 17, 23.04, then 25 or

• 4.2, - `sqrt8`, `sqrt17`, 4.8, `sqrt25`
