a) ( -6,37.0,4) . 2,5
= -6,37.( 0,4 . 2,5)
= -6,37.1
= -6,37
b) ( -0,125).(-5,3).8
= [(-0,125).8] . (-5,3)
= ( -1).(-5,3)
= 5,3
c) (-2,5).(-4).(-7,9)
= [(-2,5).(-4)] . (-7,9)
= 10. (-7,9)
= -79
d) ( -0,375). \(4\dfrac{1}{3}\) .(-2)3
=(-0,375). \(\dfrac{13}{3}\) .(-8)
=[(-0,375).(-8)] . \(\dfrac{13}{3}\)
= 3. \(\dfrac{13}{3}\)
= \(\dfrac{3}{1}\) . \(\dfrac{13}{3}\)
= 13
