Pakai cara ya, terimakasih
Penjelasan dengan langkah-langkah:
a = -3
b = 1
c = -5
Nomor 1)
= 2ab + 3bc - 4ac
= 2(-3)(1) + 3(1)(-5) - 4(-3)(-5)
= (-6)(1) + 3(-5) + 12(-5)
= (-6) + (-15) + (-60)
= -6 - 15 - 60
= -81
Nomor 2)
= (2ab - c²)²
= (2(-3)(1) - (-5)²)²
= ((-6)(1) + 5²)²
= ((-6) + 25)²
= 19²
= 19×19
= 361
