Question

simplify the radical expression sqrt3+4sqrt3

simplify the radical expression 2sqrt6+3sqrt96

simplify the radical expression (3+sqrt6)(3-sqrt6)

solve the equation 7=sqrtx +2

Answer 1

please help!!

Answer 2

\[\sqrt3+4\sqrt3=5\sqrt3\]
\[2\sqrt6+3\sqrt{96}=2\sqrt6+3*4\sqrt6=14\sqrt6\]
\[(3+\sqrt6)(3-\sqrt6)=3^2-\sqrt6^2=9-6=3\]


\[7=\sqrt{x}+2\]
\[5=\sqrt{x}\]
\[x=25\]
