Ответ:
- 25 + 27 = 52.
- 25 + 27 = 52.
- 25 − 27 = −2.
- (−0,8)² = 0,64.
- 0,5 − 1,69 = −1,19.
- 0,25 − 1,3 = −1,05.
- −6 + 0,04 = −5,96.
- (−5,8)² = 33,64.
- 36 + 0,2 = 36,2.
- 6 − 0,04 = 5,96.
- 1/9 − 8/27 = 3/27 − 8/27 = −5/27.
- (6/5)² + (1/5)³ = 36/25 + 1/125 = 180/125 + 1/125 = 181/125 = 1 56/125.
