Question

Zrobi ktoś?? Tylko zadanie 2.na dzisiaj!!!!!!!!

Answer 1

A)
( - 1,6)⁻¹ : (1/2)⁻¹ = ( - 16/10)⁻¹ : 2 = - 10/16 * 2 = - 10/8 = - 1 2/8 = - 1 1/4
b)
( - 1/4)⁻² : (2,5)⁻² = (- 4)² : (5/4)⁻² = 16 * (4/5)² = 16 * 16/25 = 256/25 = 10 6/25
c)
(- 1 1/2)⁻³ : (0,75)⁻³ = ( - 3/2)⁻³ : (3/4)³ = (- 2/3)³ : (4/3)³ = - 8/27 * 27/64 = - 8/64 =
  = - 1/8
c)
(1/5)⁻⁴ : (0,02)⁻⁴ = 5⁴ : (1/50)⁻⁴ = 5⁴ : 50⁴ = 625/6250000 = 1/10000
