I)\frac{\sqrt{14}}{2}  II)\frac{14+5 \sqrt{3}}{11}

விளக்குக:

(i) 7/√14

=\frac{7}{\sqrt{14}} \times \frac{\sqrt{14}}{\sqrt{14}}

=\frac{7 \sqrt{14}}{\sqrt{14}}

=\frac{\sqrt{14}}{2}

(ii) (5+√3)/(5-√3)

=\frac{5+\sqrt{3}}{5-\sqrt{3}} \times \frac{5+\sqrt{3}}{5+\sqrt{3}}

=\frac{(5+\sqrt{3})^{2}}{5^{2}-(\sqrt{3})^{2}}

=\frac{5^{2}+(\sqrt{3})^{2}+2 \times 5 \times \sqrt{3}}{25-3}

=\frac{25+3+10 \sqrt{3}}{22}

=\frac{14+5 \sqrt{3}}{11}
