1. \[7\sqrt{3}-4\sqrt{6}+\sqrt{48}-\sqrt{54}\]
\[\sqrt{54} = \sqrt{2*3^3}=3\sqrt{2}\sqrt{3}\]
\[7\sqrt{3}-4\sqrt{6}+\sqrt{48}-3\sqrt{2}\sqrt{3}\]
\[7\sqrt{3}-4\sqrt{6}+sqrt{2^4*3}\]
because
\[\sqrt{48}=\sqrt{2^4*3}=2^2\sqrt{3}\]
\[11\sqrt{3}-7\sqrt{6}\]
OpenStudy (astrophysics):
Use the same sort of method for the rest, good luck.
OpenStudy (oleg3321):
wait but whats the answers for both of them
OpenStudy (astrophysics):
Just simplify the square root 10 and 8 as I did on the other question.
\[\sqrt{8}=\sqrt{2^3}=2\sqrt{2} \implies \sqrt{10}*2\sqrt{2}\]
OpenStudy (astrophysics):
Finish it off.
