Question

Dados os conjuntos A-{5,6} e B={-1,3,4,5}, Determine:
A) AXB
B) A²
C) B²

Answer 1

A={5,6} e B= {-1,3,4,5}
a)AxB= {(5,-1),(5,3),(5,4),(5,5),(6,-1),(6,3),(6,4),(6,5)}
b)A²=AXA={(5,5),(5,6),(6,5),(6,6)}
c)B²=BXB={(-1,-1)(-1,3),(-1,4),(-1,5)(3,-1),(3,3),(3,4),(3,5),(4,-1),(4,3),(4,4),(4,5),(5,-1),(5,3)(5,4),(5,5)}
