Question

HELP ASAP PLEASE!!!!

Answer 1

1: negative square root of 18 (-4.2)

2: negative square root of 7 (-2.6)

3: pi/2 (1.57)

4: square root of 15 (3.9)

some are approximate calculations, but you only need the order of from smallest to largest number

Answer 2

Simplify numbers to layman terms.

`(\pi)/(2)` will be a little more than
`(3)/(2)`, since
`\pi` is 3.14.

`-√(18)` will be a little less than -4, since
`-√(18)<-√(16)`.

`√(18)` will be a little more than 4, since
`√(18)>√(16)`

`-√(7)` will be a little less than -2, since
`-√(7)<-√(4)`

Now we can order them.

`-√(18),-√(7),(\pi)/(2),√(18)`

Hope this helps.

頑張って!
