we are finding product right?

i use distributive property there
myininaya

a(b+c)=ab+ac
myininaya

\[7 \sqrt{6} \sqrt{3}+6 \sqrt{6}\] \[7 \sqrt{2 \cdot 3} \sqrt{3}+6 \sqrt{6}\]
myininaya

\[7 \sqrt{2} \sqrt{3} \sqrt{3}+6 \sqrt{6}\]

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

\[ \sqrt{6}(7 \sqrt{3}+6) = 21\sqrt{2} +6\sqrt{6} \]
