Se A e B são duas matrizes quadradas de ordem n e det ( A ) = a, det ( B ) = b, a ≠ 0 e b ≠ 0, então det[tex](4A . B^{-1})[/tex] é igual a:


a) [tex]\frac{4^{n} . a}{b}[/tex]

b) [tex]\frac{4 . n . a}{b}[/tex]

c) [tex]\frac{4 . n^{2} . a}{b}[/tex]

d) [tex]4 . a . b[/tex]

e) [tex]\frac{4 . a}{b}[/tex]
