Why does it not times the 2 (the radicand) as well?

Since it was in the parenthesis shouldn't it be multiplied too?

or do you not times the radicand when finding the perimeter of a rectangle?

Where do you have doubt in this? \[2(\sqrt{128}+\sqrt{200})= 2(8 \sqrt 2+ 10 \sqrt 2)= 2(18 \sqrt 2)=36 \sqrt 2\]

2(√128+√200)=2(8√2+10√2)=2(18√2)=36√2 or 36√4?

I just need to know if you times the radicand?

Well, wouldn't you ask that in the other question ask the person who posted it?

ash2326Best ResponseYou've already chosen the best response.1
you have \[2\times18 \sqrt {2}\] you'll just multiply it by 18 \[36\sqrt 2\]

It was posted a while ago... and I did

@EvonHowell it's ok to ask as a new post. It's related to maths
 one year ago

that1chickBest ResponseYou've already chosen the best response.1
so in 2(18√2) you would only times the 18 by 2?

@that1chick If you have \[2\sqrt 2\] then it's two times the radicand
 one year ago

ash2326Best ResponseYou've already chosen the best response.1
yes, if you have \[2\times (4\times 6)\] Would you multiply it to both 4 and 6?

Yes, I know it is I was just saying.. LOL but that question was asked 5 Months ago so I understand now :)

@that1chick do you get my point?

that1chickBest ResponseYou've already chosen the best response.1
Ok I get it... they shouldnt have put it in parenthesis. Thank you
 one year ago

ash2326Best ResponseYou've already chosen the best response.1
Nope, they can put in parenthesis. If you have \[a(b+c)=a\times b+a\times c\] \[a(b\times c)=(a\times b)c=a\times b\times c\]

are you saying that it didnt change the radicand because it was applied to the value being times by the radical and therefor would be applied that way
 one year ago

ash2326Best ResponseYou've already chosen the best response.1
It's applied to the whole term if you have 2 *(4*6) you apply 2 to either 4 or 6 not both. In our case we have a radical so it's applied to 18, it can be applied to radical also \[2\times (18\sqrt {2})=18\times 2\sqrt 2\] Take the 2 inside \[18\times \sqrt{4\times 2}=18\sqrt 8\] radical is just a no.

Oh okay... x the other value makes it towhere you dont have to simplify again... I get it now, thank you
