Question

TOLONG BANTU

Itu digambar sudah saya isi, beberapa belum, saya ragu dengan jawaban saya
Tolong diperiksa jawaban saya benar atau tidak, untuk yang belum diisi tolong bantu dijawab

Answer 1

(-1)³ = (-1)(-1)(-1)
= (1)(-1)
= -1

(-1)² = (-1)(-1)
= 1

(-1)¹ = -1

(-1)⁰ = 1

(-1)⁻¹ = 1/(-1)
= -1

(-1)⁻² = 1/(-1)²
= 1/1
= 1

(-1)³ = 1/(-1)³
= 1/-1
= -1

==========

(1/2)³ = 1³ / 2³ = 1/8
(1/2)² = 1² / 2² = 1/4
(1/2)¹ = 1/2
(1/2)⁰ = 1
(1/2)⁻¹ = 1 / (1/2)¹ = (2/1)¹ = 2
(1/2)⁻² = 1 / (1/2)² = (2/1)² = 4
(1/2)⁻³ = 1 / (1/2)³ = (2/1)³ = 8

==========

(2/3)³ = 2³ / 3³ = 8 / 27
(2/3)² = 2² / 3² = 4 / 9
(2/3)¹ = 2/3
(2/3)° = 1
(2/3)⁻¹ = 1 / (2/3)¹ = 3/2
(2/3)⁻² = 1 / (2/3)² = (3/2)² = 9 / 4
(2/3)⁻³ = 1 / (2/3)³ = (3/2)³ = 27 / 8
