OpenStudy (jdoe0001):

see the drawing?

OpenStudy (anonymous):

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

@jdoe0001

OpenStudy (jdoe0001):

\(\bf 2\sqrt{5}(3\sqrt{2}+3\sqrt{5}) \implies (2\sqrt{5} \times 3\sqrt{2})+(2\sqrt{5} \times3\sqrt{5})\)

OpenStudy (anonymous):

\[\sqrt{10} 5+5\sqrt{25}\] I got it down to this

OpenStudy (jdoe0001):

$$ \bf 2\sqrt{5}(3\sqrt{2}+3\sqrt{5}) \implies (2\sqrt{5} \times 3\sqrt{2})+(2\sqrt{5} \times3\sqrt{5})\\ 6\sqrt{10}+6\sqrt{25}\\ 25 = 5^2 \implies \sqrt{5^2} =5\\ 6\sqrt{10}+6(5) \implies 6\sqrt{10}+30 \implies 6(5+\sqrt{10}) $$

thank you!
