Question

Zapisz w postaci potęgi i oblicz .

a) ((-1,2)²)⁻¹

b) (((3 12/17 )⁵)⁰)⁻¹¹

c) (((-2,49)¹)⁻¹)⁻¹

d) ((-½)²)⁻¹ × (-½)

Answer 1

A) ((-1,2)²)⁻¹=(-1,2)⁻²=(-6/5)⁻²=-36/25=-1,44

b) (((3 12/17 )⁵)⁰)⁻¹¹=(3 12/17)⁰=1
(liczba do pot. ⁰ (zero) =1)

c) (((-2,49)¹)⁻¹)⁻¹=(-2,49)¹=-2,49

d) ((-½)²)⁻¹ × (-½)=(-½)⁻² × (-½)=(-½)⁻³=-8
