soal matematika jawab pake cara ya help me buat latian belajar
Jawab:
16 (E)
Penjelasan dengan langkah-langkah:
Jika matriks A = [tex]\left[\begin{array}{ccc}a&b\\c&d\end{array}\right][/tex], B = [tex]\left[\begin{array}{ccc}e&f\\g&h\end{array}\right][/tex] dan A= B, maka:
- a = e
- b = f
- c = g
- d = h
Diketahui bahwa P = [tex]\left[\begin{array}{ccc}8&2a\\3&c\end{array}\right][/tex], Q = [tex]\left[\begin{array}{ccc}2a&b\\3&2b\end{array}\right][/tex] dan P = Q, maka:
- 8 = 2a
4 = a
a = 4
- 2a = b
2(4) = b
8 = b
b = 8
- 3 = 3
- c = 2b
c = 2(8)
c = 16
