Question

474. Сравните: 1) (-10)³ и 10³; 2) (-0,1)² и 0,1²; 3) (−2)³ и (−3)²; 4) (-0,5)² и (-0,5)³; ИЯ* 5) 1,2² и (-1,2)²; 6) (-1) ⁹⁹ и (-1)¹00 решите умоляю за 99 балов​

Answer 1

Пошаговое объяснение:

Отрицательное число в чётной степени даёт положительный результат

Отрицательное число в нечётной степени даёт отрицательный результат.

(-10)³ < 10³

(-0,1)² = 0,1²

(-2)³ < (-3)²

(-0,5)² > (-0,5)³

1,2² = (-1,2)²

(-1)⁹⁹ < (-1)¹⁰⁰

Answer 2

Ответ:

(-10)³ < 10³

(-0,1)² = 0,1²

(−2)³ < (−3)²

(-0,5)² > (-0,5)³

1,2² = (-1,2)²

(-1) ⁹⁹ = (-1)¹

Пошаговое объяснение:

(−2)³ = -8

(−3)² = 9

тут видно что квадрат убрал знак минуса, а куб нет

Answer 3

1. (-10)³ = -1000 10³ = 1000 (-10)³ is equal to -1000, while 10³ is equal to 1000. They have the same magnitude but opposite signs.

2. (-0.1)² = 0.01 0.1² = 0.01 (-0.1)² is equal to 0.01, just like 0.1². Both expressions yield the same positive result.

3. (-2)³ = -8 (-3)² = 9 (-2)³ is equal to -8, whereas (-3)² is equal to 9. The two expressions have different magnitudes and signs.

4. (-0.5)² = 0.25 (-0.5)³ = -0.125 (-0.5)² is equal to 0.25, while (-0.5)³ is equal to -0.125. The two expressions have different magnitudes and signs.

5. 1.2² = 1.44 (-1.2)² = 1.44 1.2² is equal to 1.44, and (-1.2)² is also equal to 1.44. Both expressions yield the same positive result.

6. (-1)⁹⁹ = -1 (-1)¹⁰⁰ = 1 (-1)⁹⁹ is equal to -1, whereas (-1)¹⁰⁰ is equal to 1. The two expressions have different signs.

Note: In the calculations, the exponentiation is performed before considering the negative sign, so (-1)⁹⁹ is equal to -1 and (-1)¹⁰⁰ is equal to 1.
