Answer 3

umm 9

Answer 4

we'll see how it goes, but 9 sounds a bit too high

Answer 5

but let's do a few

Answer 6

okay

Answer 7

\[\sqrt{(+3)^2)^2}\]

Answer 8

I have to simplify it

Answer 9

seems like a typo...just +3 ?

Answer 10

\[\sqrt{(x+3)^2}\] sorry

Answer 11

ok from last night, I was trying to get you to see that square roots undo squaring

Answer 12

basically, you take any positive number and you square it

then if you take the square root of that result, you get back to the original positive number

Answer 13

example

5^2 = 25

sqrt(25) = 5

Answer 14

so that's why sqrt(x^2) = x when x is some positive number

Answer 15

okay so I square 3

Answer 16

so if you take some unknown number x+3 and you square it, you get (x+3)^2

Answer 17

then take the square root of that to get ???

Answer 18

that is where I get lost at

Answer 19

do you see how sqrt(x^2) = x

Answer 20

yes

Answer 21

so think of x+3 as a number (just like x is)

Answer 22

if you want, let z = x+3

so sqrt( (x+3)^2 ) is the same as sqrt( z^2 )

Answer 23

okay that is 4 right

Answer 24

idk how you're getting 4

Answer 25

ohh sorry

Answer 26

what does sqrt( z^2 ) simplify to

Answer 27

z^2

Answer 28

@jim_thompson5910

Answer 29

no

Answer 30

square roots undo squaring

Answer 31

okay so wat would it be

Answer 32

Are you sure you understand how

\[\Large \sqrt{x^2} = x\]

when x is positive

Answer 33

I DONT THINK SO

Answer 34

ok replace x in that equation with any number you want

Answer 35

pick any positive number and tell me which one you pick
