Answer 1

1) (36,5² - 27,5²)=(36,5-27,5)(36,5+27,5)=9*64

2) 57³+33³=(57+33)(57² -57*33 + 33²)=90(57² - 57*33 + 33²)

3) [90(57² - 57*33 + 33²)]/90=57² - 57*33 + 33²

4) 57² - 57*33 + 33² - 57*33 = 57² - 2*57*33 + 33² =(57-33)²=24²

5) (9*64) : 24² =(9*4*4*4) : (4*6)² =(9*4*4*4) : (4*4*6*6)=
    =(9*4):(6*6)=36:36=1

Ответ: 1.
