Best ResponseYou've already chosen the best response.1Why does it not times the 2 (the radicand) as well?

Best ResponseYou've already chosen the best response.1Since it was in the parenthesis shouldn't it be multiplied too?

Best ResponseYou've already chosen the best response.1or do you not times the radicand when finding the perimeter of a rectangle?

Best ResponseYou've already chosen the best response.1Where do you have doubt in this? \[2(\sqrt{128}+\sqrt{200})= 2(8 \sqrt 2+ 10 \sqrt 2)= 2(18 \sqrt 2)=36 \sqrt 2\]

Best ResponseYou've already chosen the best response.12(√128+√200)=2(8√2+10√2)=2(18√2)=36√2 or 36√4?

Best ResponseYou've already chosen the best response.1I just need to know if you times the radicand?

Best ResponseYou've already chosen the best response.0Well, wouldn't you ask that in the other question ask the person who posted it?

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

Best ResponseYou've already chosen the best response.1@EvonHowell it's ok to ask as a new post. It's related to maths

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

Best ResponseYou've already chosen the best response.1@that1chick If you have \[2\sqrt 2\] then it's two times the radicand

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

Best ResponseYou've already chosen the best response.0Yes, I know it is I was just saying.. LOL but that question was asked 5 Months ago so I understand now :)

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

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

Best ResponseYou've already chosen the best response.1are 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

ash2326

Best ResponseYou've already chosen the best response.1It'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.

Best ResponseYou've already chosen the best response.1Oh okay... x the other value makes it towhere you dont have to simplify again... I get it now, thank you
