Answer:a=\frac{11}{7} and b=\frac{6}{7}

Step-by-step explanation:

\frac{3+\sqrt{2}}{3-\sqrt{2}}=a+b\sqrt{2}

Rationalising ,

\frac{3+\sqrt{2} }{3-\sqrt{2}} *\frac{3+\sqrt{2} }{3+\sqrt{2} }=\frac{(3+\sqrt{2})^2 }{3^2-(\sqrt{2)^2} }=\frac{9+2+6\sqrt{2} }{9-2}=\frac{11}{7} +(\frac{6}{7})\sqrt{2}

On comparing we get

a=\frac{11}{7} and b=\frac{6}{7}
