Answer 1

$\displaystyle \frac{37^2-23^2}{37^2-2*37*23+23^2} = \frac{(37-23)(37+23)}{(37-23)^2}= \frac{37+23}{37-23}= \frac{60}{14} = 4 \frac{2}{7}$

Answer 2

$\frac{37^2-23^2}{37^2-2*37*23+23^2} = \frac{(37-23)(37+23)}{(37-23)^2} = \frac{37+23}{37-23} = \frac{60}{14} = 4\frac{2}{7}$ Ответ: $4\frac{2}{7}$.
