someone please help see drawing

OpenStudy (anonymous):

\[\sqrt{6}(\sqrt{3}+5\sqrt{2})\]

OpenStudy (ivettef365):

use distributive property

OpenStudy (anonymous):

do I square it first?

OpenStudy (ivettef365):

multiply only what is inside the squares, likes sqrt6 x sqrt 3 = sqrt18 then sqrt6 x 5sqrt2 = 5sqrt12

OpenStudy (ivettef365):

now that you have sqrt18 that is sqrt(9x2)

OpenStudy (anonymous):

\[\sqrt{18}+5\sqrt{12}\] like this?

OpenStudy (ivettef365):

correct

OpenStudy (ivettef365):

now you have sqrt18 which is sqrt(9x2), so what is the sqrt9

OpenStudy (anonymous):

3

OpenStudy (ivettef365):

ok so pull out the 3 and you have 3sqrt2 now do the same with 5sqrt12

OpenStudy (ivettef365):

that is equal to 5sqrt(4x3)

OpenStudy (anonymous):

2.23 is five squared?

OpenStudy (ivettef365):

just pull out the 2 because sqrt4 = 2 so you have 5(2)sqrt3

OpenStudy (ivettef365):

now the final answer for the problem is 3sqrt2 + 10sqrt3

OpenStudy (anonymous):

can you draw that out?

OpenStudy (ivettef365):

you draw it and I tell you if is ok

OpenStudy (anonymous):

nvm I got it it is this \[3\sqrt{2}+10\sqrt{3}\]

OpenStudy (ivettef365):

that is correct

OpenStudy (anonymous):

I might have some more questions later do you mind if I tag you?
