Proszę o obliczenie 3kl gimn (kolejne kroki co obliczamy tez powinny byc)
a) (-5⁻¹+5)² - (¼)⁻¹ : 5⁻² - 5⁻²
b) [(x⁻⁴ * x⁻²)⁻⁵ : (x⁻⁶ *x⁻⁴)⁻²] : [x⁻⁸ : x⁻⁹]
Proszę chociaż o podpunkt a

a) (-5⁻¹+5)² - (¼)⁻¹ : 5⁻² - 5⁻²=
=(-1/5+5)² - 4 : (1/25) - (1/25)=(4 i 4/5)²-100-1/25=576/25-100-1/25=575/25-100=23-100=-77
b) [(x⁻⁴ * x⁻²)⁻⁵ : (x⁻⁶ *x⁻⁴)⁻²] : [x⁻⁸ : x⁻⁹]=
=[(x⁻⁶)⁻⁵ : (x⁻¹⁰)⁻²] : [x]=[x³⁰ : x²⁰] : [x]=x¹⁰:x=x⁹
