Ответ:
1) \frac{59}{104} 2) \frac{503^{2}-161604}{} 3)\frac{65}{42}
Пошаговое объяснение:
1) \frac{(37-22)*(37+22)}{(43-17)*(43+17)} = \frac{15*59}{26*60}
= \frac{885}{1560} = \frac{59}{104}
3) \frac{(87-43)*(87+43)}{2^{12}-(10*2)^{2}} = \frac{44*130}{2^{12}-10^{2}*2^{2}} = \frac{5720}{(1024-100)*4} = \frac{130}{21*4} = \frac{65}{21*2} = \frac{65}{42}
