oblicz stosując własności potęgi [(1 3/4)do potęgi -7*(1 3/4)do pot. - 4 ]do pot. 1/2 : (2/5) do pot. - 5 =

[(1 ¾)⁻⁷ *(1 ¾)⁻⁴]¹/² : (²/₅)⁻⁵ = [(1 ¾)⁻⁷⁻⁴]¹/² : (⁵/₂)⁵= =[(⁷/₄)⁻¹¹]¹/² : (⁵/₂)⁵= (⁴/₇)¹¹/² : (⁵/₂)⁵=(2¹¹)/(7¹¹/²) * (2⁵)/(5⁵)= =(2¹¹)* (2⁵)/(7¹¹/²)*(5⁵)= =2¹⁶/ /(7¹¹/²)*(5⁵) (⁴/₇)¹¹/² =(2²/7)¹¹/²=(2²*¹¹/²)/(7¹¹/²)=(2¹¹)/(7¹¹/²)
