Tolong bantu tugas iniiii

Menggunakan perkalian skalar.
•3a = 3 (2 3 1 4)
= (6 9 3 12)
•5b = 5 (7 2 2 5)
= (35 10 10 25)
•2c = 2 (1 3 4 5)
=(2 6 8 10)
3a+5b+2c = (6 9 3 12) + (35 10 10 25) + (2 6 8 10)
= (43 25 21 47)
Semoga paham ya^

3a+5b+2c
= 3 (2 3 1 4) + 5 (7 2 2 5) + 2 (1 3 4 5)
= (6 9 3 12) + (35 10 10 25) + (2 6 8 10)
= (43 25 21 47)
