Question

1) (-2)²= 2) (-3)³= 3) (-2/7)²= 4) (-0,3)³= 5) (-1)²= 6) (-1)³= помогите пожалуйста

Answer 1

Ответ:

Пошаговое объяснение:

Степень числа указывает сколько раз нужно умножить число на само себя :

(-2)² = -2 * (-2) = 4

(-3)³ = -3 * (-3) * (-3) = -27

(-2/7)² = -2/7 * (-2/7) = 4/49

(-0,3)³ = -0,3 * (-0,3) * (-0,3) = -0,027

(-1)² = -1 * (-1) = 1

(-1)³ = -1 * (-1) * (-1) = -1

Answer 2

Ответ:

Пошаговое объяснение:

1) (-2)²= -2*-2=4

2) (-3)³= -3*-3*-3=9*-3=-27

3) (-2/7)²= -2/7*-2/7=4/49

4) (-0,3)³= -0,3*-0,3*-0,3=0,9*-0,3=-0,027

5) (-1)²=-1*-1=1

6) (-1)³=-1*-1*-1=-1

Answer 3

1) (-2)²

To calculate (-2)², we square the number -2.

(-2)² = (-2) * (-2) = 4

So, (-2)² is equal to 4.

2) (-3)³

To calculate (-3)³, we cube the number -3.

(-3)³ = (-3) * (-3) * (-3) = -27

So, (-3)³ is equal to -27.

3) (-2/7)²

To calculate (-2/7)², we square the fraction -2/7.

(-2/7)² = (-2/7) * (-2/7) = 4/49

So, (-2/7)² is equal to 4/49.

4) (-0.3)³

To calculate (-0.3)³, we cube the decimal number -0.3.

(-0.3)³ = (-0.3) * (-0.3) * (-0.3) = -0.027

So, (-0.3)³ is equal to -0.027.

5) (-1)²

To calculate (-1)², we square the number -1.

(-1)² = (-1) * (-1) = 1

So, (-1)² is equal to 1.

6) (-1)³

To calculate (-1)³, we cube the number -1.

(-1)³ = (-1) * (-1) * (-1) = -1

So, (-1)³ is equal to -1.
