Answer 1

1 załącznik:

Zad. 7.
d) (-1⅓)²¹ x (0,75)²¹ - (0,5)⁰ : 2⁰ = (-1⅓ x ¾)²¹ - 1 : 1 = (-1) - 1 : 1 = (-1) - 1 = (-2)

Zad. 8.
a) [(-1)²]³¹ = (-1)⁶² = 1
(1³)¹⁵ = (1)⁴⁵ = 1
[-(-1)⁷]⁴ = (1⁷)⁴ = 1²⁸ = 1

b) [(-0,1)²]³ = (-0,1)⁶ = 0,000001
(0,2³)² = (0,2)⁶ = 0,000064
[-(-0,1)²]³ = (0,1)⁶ = 0,000001

c) (-3a²b)³ = (-27a⁶b³)
(-ab²cd²)⁵ = (ab¹⁰cd¹⁰)
[(½ab)³ x (2ab²)²]³ = (1/512a²⁷b²⁷) x (64a⁸b⁶⁴)
