Question

Simplify this radical expression. Use absolute values when needed....


Answer choices:
A) x^2+9
B) |x+3|
C) x+3
D) |x^2+9|

Answer 1

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

Answer 2

so will be C).

but can you tell me why ?

Answer 3

so can you writing please sqrt(x) = ?

using exponent form

Answer 4

so you dont like cooperating anything please ?

Answer 5

so than sqrt(x)=x^(1/2)

yes ?

Answer 6

Im sorry i was trying to figure it out. i dont understand :/

Answer 7

so with this example i like to make you understanding all right

hopw do you know that sqrt(x)=x^(1/2)

where the denominator of fraction from the exponent always mean the indice of radical

Answer 8

so the same cuberoot(x)=x^(1/3)

ok ?

Answer 9

so where is Zuni ? please

Answer 10

i am from Europe country Hungary

Answer 11

okayy... i think i am kind of understanding what you are trying to say with the problem... Zuni is in the United States in the state of New Mexico :) Wow you are far far away!

Answer 12

so than your exercise will be using exponentialy form

sqrt(x+3)^2 =((x+3)^2)^(1/2)

so right ?

do you understand it sure ?

Answer 13

and yes i am so far far away ,you see it right

Answer 14

yes! :) !!

Answer 15

do you know it where is Hungary ?

yes ?

but there you can simplifie again

Answer 24

((x+3)^2)^(1/2) =(x+3)^((2*1)/2) =(x+3)^1 =x+3

ok ?

Answer 25

hope so much that you can understanding all right sure
