Question

PLLEEEZZ HELP!! solve:

Answer 1

thats what you would solve:)

Answer 2

Can you factor 108?

Answer 3

... i think so... 6√3??

Answer 4

108
Pull all perfect square roots out from under the radical. In this case, remove
the 6 because it is a perfect square.
6 3

Answer 5

good, \[\Large \sqrt{108}=6\sqrt{3}\]

Answer 6

6√3

Answer 7

now simplify \[\Large \sqrt{8}\]

Answer 8

2√2

Answer 9

good, so \[\Large 3\sqrt{8} = 3*2\sqrt{2} = 6\sqrt{2}\]

Answer 10

what about the last one

Answer 11

\[\sqrt{27}\]

Answer 12

3√3

Answer 13

perfect

Answer 14

Now combine like terms

Answer 15

so how would the answer look??

Answer 16

We go from

\[\Large \sqrt{108}-3\sqrt{8}-\sqrt{27}\]

to

\[\Large 6\sqrt{3}-6\sqrt{2}-3\sqrt{3}\]


Now let x = sqrt(3) and y = sqrt(2) to get


6x - 6y - 3x


From here, combine like terms. What do you get?

Answer 17

9x-6y??

Answer 18

6x - 3x is???

Answer 19

oh 3x!!!! i didnt see the- hhaha silly me!:P so thats the answer??

Answer 20

not yet

so

6x - 6y - 3x

becomes

3x - 6y


Now replace x with sqrt(3) and y with sqrt(2) (remember we made these assignments above)

to get

\[\Large 3\sqrt{3}-6\sqrt{2}\]

Answer 21

oh ok! then that is the answer???? haha

Answer 22

yes

Answer 23

hahha ok thanks a million!! <3

Answer 24

you're welcome
