what is ur question

OpenStudy (anonymous):

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

OpenStudy (anonymous):

\[\sqrt{18} + 5\sqrt{2}\] \[\sqrt{18} + \sqrt{50}\]

OpenStudy (anonymous):

\[A. 3\sqrt{3} + 15\sqrt{2}\] \[B. 3\sqrt{2}+5\sqrt{12}\] \[C. 3\sqrt{2}+10\sqrt{3}\]

OpenStudy (anonymous):

oh that will be B \[{\sqrt{18}} + \sqrt{50}\] \[\sqrt{9 \times2} + \sqrt{25 \times2}\] \[3\sqrt{2}+5\sqrt{2}\]

OpenStudy (anonymous):

did u make a typing error on B?

OpenStudy (anonymous):

No i did not

OpenStudy (anonymous):

so you multiply it out and you get: \[\sqrt6 *\sqrt 3+ \sqrt6*5\sqrt2\] which becomes: \[\sqrt18+5\sqrt12\] which is also equal to: \[\sqrt{9*2} +5 \sqrt{3*4}\] you know that \[\sqrt9 = 3, and \sqrt4=2\] so your expression simplifies to: \[3\sqrt2 +10 \sqrt3\] so the answer is C.. got it?

OpenStudy (anonymous):

my mistake

OpenStudy (anonymous):

the answer is still B

OpenStudy (anonymous):

correct, C or B works. However, I think it depends on the question. Maybe C is the most simplified form of the expression.?

OpenStudy (anonymous):

Ok..

OpenStudy (anonymous):

YEAH true C is the most correct .take C

OpenStudy (anonymous):

Ok
