Question

dados os conjuntos : A= -2,4 b=3,-5 c= 5,6,7 d 1,2,3 e e= 8,9 , determine. a) A×b b)e×d c) b×c d) b×b e) c×d f) e elevado a 2
f) a×d g) b×d

Answer 1

a) AxB=(-2,4)x(3,-5) = (-6,-20)
b)ExD=(8,9)(1,2,3) = x
c)BxC=(3,-5)(5,6,7)=x
d)BxB=(3,-5)(3,-5)=(9,25)
e)CxD=(5,6,7)(1,2,3)=(5,12,21)
f)AxD=x
g)BxD=x
