Question

Use combinations of Properties 1 and 2 for radicals to simplify the following problem as much as possible. Assume the variable represents a positive number.

Answer 1

\[\frac{ 4 \sqrt{18a^2b^2}}{ \sqrt{9} }\]

Answer 2

Answer 3

hey cookie, how are you ?
could you move the denominator under the sq.root of the numerator?

Answer 4

Hi :) I'm good, you?
What do you mean?

Answer 5

\[4\sqrt{(18a ^{2}b ^{2})/9}\]

Answer 6

then divide 18 by 9, you get 2

Answer 7

a^2 & b^2 becomes a & b

Answer 8

then take a^2 b^2 out of the radical and you'll be left with sq.root of 2

Answer 9

yes that's correct

Answer 10

What d o I do with the 4?

Answer 11

it stays, the answer looks like this

\[4ab \sqrt{2}\]

Answer 12

Got it !

Answer 13

am just not sure what your book says about property 1 and 2 of radicals, need to paste that if the answer isn't what they expect

Answer 14

I don't even use my book lol it's all online, including the ebook.

Answer 15

Thanks!

Answer 16

I guess then refer to your online ebook for the properties as I don't have a reference to it

no worries
cheers

Answer 17

You want me to look for them & paste them on here?

Answer 18

ok that will be good, thanks

Answer 19

found them!!

Answer 20

what do they state?

Answer 21

cool, so can you see how we applied both prop's ?

Answer 22

prop 1 is when you took a^2 and b^2 out of the sq.root and prop.1 when we moved the 9 under the same sq.root with the 19.

Answer 23

prop 1 is when you took a^2 and b^2 out of the sq.root and prop.1 when we moved the 9 under the same sq.root with the 19.

Answer 24

Oh, I see it
