Ответ:
[tex] \frac{a - 64}{ \sqrt{a } - 8} = \frac{( \sqrt{a} - 8)( \sqrt{a} + 8)}{ \sqrt{a} - 8 } = \sqrt{a} + 8[/tex]
[tex] \frac{ \sqrt{11} - 11}{ \sqrt{11} } = \frac{( \sqrt{11} - 11) \sqrt{11} }{ \sqrt{11 \sqrt{11} } } = \frac{11 - 11 \sqrt{11} }{11} = \frac{11(1 - \sqrt{11)} }{11} = 1 - \sqrt{11} [/tex]
