Doprowadź wyrażenie do najprostszej postaci [(a⁴)⁵:(a×b)⁸]:[(2a⁷b³-b³a⁷):b¹¹]

[(a⁴)⁵:(a×b)⁸]:[(2a⁷b³-b³a⁷):b¹¹]=[a²⁰:(a⁸×b⁸)]:[(2a⁷b³-b³a⁷):b¹¹]= =[a²⁰:a⁸b⁸]:[(2a⁷b³-a⁷b³):b¹¹]=[a²⁰⁻⁸×b⁸]:[a⁷b³:b¹¹]= =[a¹²×b⁸]:[a⁷×b³⁻¹¹]=a¹²b⁸:a⁷b⁻⁸= a¹²⁻⁷×b⁸⁻⁻⁸=a⁵×b⁸⁺⁸=a⁵b¹⁶

[(a⁴)⁵:(a×b)⁸]:[(2a⁷b³-b³a⁷):b¹¹] = [ a⁴*⁵: a⁸*b⁸]:[(2a⁷b³- a⁷b³) : b¹¹] = [ a^20 : a⁸*b⁸]:[a⁷b³ : b¹¹] = [ a^12 : b⁸]:[a⁷:b⁸] = [ a^12 : b⁸]*[b⁸:a⁷] = a⁵
