Jika a = -3, b = 1 ,dan c = -5 hitunglah: a.2a^2 + 2bc = b.a^2b^2 - 2 b^2c = Mohon dijawab sekarang juga yah

a. 2a^2+ 2bc
2.1^2 + 2.1.-5
4 - 10 = -6
b. a^2b^2 - 2b^2c
=9.1 + 10
=10

kayaknya

a. 2×(-3)^2 + 2×1×(-5)
= 2×9 + (-10)
= 18-10
= 8
b. (-3)^2 × 1^2 - 2×1^2 × (-5)
= 9 × 1 - (-10)
= 9+10
= 19
Maaf ya klu slah soal pangkat yg bagian a kurang jelas
