Question

(sorry i need a lot of help lol) (see pic(its gonna take me a min to get it up there))

Answer 1

\[\sqrt{12}-3\sqrt{3}\]
12 perfect square is 4 square root it 2
so that would be \[4\sqrt{3}-3\sqrt{3}\]
i thought it would be \[1\sqrt{3}\]
but that's not a choice?

Answer 2

You almost had it ...but remember

\[\sqrt{12} = \sqrt{4}\sqrt{3} = 2\sqrt{3}\]

Remember you have to put it like that first...

Answer 3

o okay then it would be \[2\sqrt{3}\] right?

Answer 4

Right...for the √12 part yeah....

so now we have

\[\large 2\sqrt{3} - 3\sqrt{3} = ?\]

Answer 5

\[4\sqrt{3}\]
\[-\sqrt{3}\]
\[3\sqrt{9}\]
these are the choices @johnweldon1993

Answer 6

Mmhmm I see it :) lol

\[2\sqrt{3} - 3\sqrt{3} = -1\sqrt{3}\]

Is that -1 really necessary there? Nope not at all..it is just

\[\large -\sqrt{3}\]

Answer 7

ooops i made a simple mistake, uhh i make those often but when i see them i understand what i did lol thank you! (AGAIN)

Answer 8

haha don't worry about it :) Good work :)
