Uprav v \( R \) a urči podmínky: \( \frac{a^2 - b^2}{a^2} \times \frac{a}{(a+b)^2} = \frac{(a-b) \times (a+b)}{a^2} \times \frac{a}{(a+b)^2}  = \frac{(a-b) \times (a+b) \times a^2} {{a\times(a+b)^2}} = \frac{(a-b) \times a^2} {{a\times(a+b)}} = \frac{(a-b) \times a} {a+b} = \frac{a^2-ab} {a+b}; a \neq 0; a \neq -b \)

Uprav výraz a napiš podmínky: \( \frac{(a - \frac{1}{a})^{-2} + (a + \frac{1}{a})^{-2}}{(a - \frac{1}{a})^{-2} - (a + \frac{1}{a})^{-2}} = \frac{\frac{1}{(a - \frac{1}{a})^{2}} + (a + \frac{1}{a})^{-2}}{(a - \frac{1}{a})^{-2} - (a + \frac{1}{a})^{-2}} =  \)
