Step-by-step explanation:

1) 1/root7

multiply and divide by $\sqrt{7}+\sqrt{6}$

$\frac{1}{\sqrt{7}-\sqrt{6}   }$ ×$\frac{\sqrt{7}+\sqrt{6}  }{\sqrt{7}+\sqrt{6}  }$

$\frac{\sqrt{7}+\sqrt{6}  }{(\sqrt{7})^{2} -(\sqrt{6}) ^{2} }$

$\frac{\sqrt{7}+\sqrt{6}}{7-6}$

$\frac{\sqrt{7}+\sqrt{6}}{1} \\ \\ \sqrt{7}+\sqrt{6}$

like these only we can do remaining
