(0 4) (3 -2)
tentukanlah?
a. 2A+B
b.A×2B
c.3B-A
Jika diketahui matriks A=(4 2) dan B=(0 -1)
A. 2(4 2) + (0 -1)
(0 4) (3 -2)
= (8 4) + (0 -1)
(0 8) (3 -2)
= (8 3)
(3 6)
b.(4 2) x 2 (0 -1)
(0 4) (3 -2)
= (4 2) x (0 -2)
(0 4) (6 -4)
=(0 -4)
(0 -16)
c.3 (0 -1) – ( 4 2)
(3 -2) ( 0 4)
= (0 -3) – (4 2)
(9 -6) (0 4)
=(-4 -5)
(9 -10)
semoga membantu ya
