It isnt so clear
myininaya (myininaya):
\[\sqrt{3} (3+2 \sqrt{5}) \sqrt{6}(7 \sqrt{3}+6)?\]
myininaya (myininaya):
we are finding product right?
OpenStudy (anonymous):
\[√6(7√3 + 6)\] thats the one i still need help on
OpenStudy (anonymous):
myinaya it itwo separate equations

distributing and simplifying
myininaya (myininaya):
\[\sqrt{6}(7 \sqrt{3}+6)\]
myininaya (myininaya):
\[\sqrt{6} \cdot 7 \sqrt{3}+\sqrt{6} \cdot 6 \]
myininaya (myininaya):
i use distributive property there
myininaya (myininaya):
a(b+c)=ab+ac

\[7 \sqrt{6} \sqrt{3}+6 \sqrt{6}\]
\[7 \sqrt{2 \cdot 3} \sqrt{3}+6 \sqrt{6}\]
myininaya (myininaya):
\[7 \sqrt{2} \sqrt{3} \sqrt{3}+6 \sqrt{6}\]
OpenStudy (anonymous):
is the "c" a "3"??
myininaya (myininaya):
\[7 \sqrt{2}(3)+6 \sqrt{6}=7(3) \sqrt{2}+6 \sqrt{6}=21 \sqrt{2}+6 \sqrt{6}\]
OpenStudy (anonymous):
\[ \sqrt{6}(7 \sqrt{3}+6) = 21\sqrt{2} +6\sqrt{6} \]

Distributive property holds because they are rationals.
