Question

Can anyone help me, please ?

Answer 1

\[\Large \sqrt{48}\]


\[\Large \sqrt{16*3}\]


\[\Large \sqrt{16}*\sqrt{3}\]


\[\Large 4*\sqrt{3}\]


So \[\Large \sqrt{48} = 4*\sqrt{3}\]

Answer 2

Use this idea to simplify the other roots. Then combine like terms.

Answer 3

Tell me what you get when you simplify them.

Answer 4

Okay... one second.

Answer 5

alright

Answer 6

So it is either b or c.

Answer 7

what makes you say that?

Answer 8

OH, wait ..it's A.
I think.

Answer 9

\[\Large \sqrt{75}\]


\[\Large \sqrt{25*3}\]


\[\Large \sqrt{25}*\sqrt{3}\]


\[\Large 5*\sqrt{3}\]


This means \[\Large \sqrt{75} = 5*\sqrt{3}\]

Answer 10

\[\Large \sqrt{192}\]


\[\Large \sqrt{64*3}\]


\[\Large \sqrt{64}*\sqrt{3}\]


\[\Large 8*\sqrt{3}\]


This means \[\Large \sqrt{192} = 8*\sqrt{3}\]

Answer 11

I'm still confused.

Answer 12

Put it all together to get...


\[\Large \sqrt{48}-\sqrt{75}+\sqrt{192}\]


\[\Large 4*\sqrt{3}-5*\sqrt{3}+8*\sqrt{3}\]


\[\Large (4-5+8)*\sqrt{3}\]


\[\Large 7\sqrt{3}\]


So \[\Large \sqrt{48}-\sqrt{75}+\sqrt{192}=7\sqrt{3}\]

Answer 13

That's where I got confused, in the parenthesis.

Answer 14

you basically factor out the GCF sqrt(3) and you combine like terms

Answer 15

See that's what I was missing,.

Answer 16

does it all make sense now?

Answer 17

Um, yes I understand it beteter.

Answer 18

*better.

Answer 19

alright that's great
