jika p= 3,q = -4 dan r = -2 hitunglah a. 2pr pangkat dua b. p(pangkat 2) q pangkat 2 r (p2q2r) c. p3q2r3

a. 2pr^2
{2×3×(-4)} {2×3×(-4)}
-24 × (-24)
576
b.3^2 × (-4)^2 × (-2) {3×2×(-4)×2×(-2)}
9×16×(-2)×{-6×(-8)×(-4)}
144×(-2) × {48×(-4)}
-288×(-192)
55.296
c. 3×3×(-4)×2×(-2)×3
9×(-8)×(-6)
-72×(-6)
432




maaf kalau salah

a)
2pr²
= 2.3.(-2)²
= 2.3.4
= 24

b)
p²q²r
= 3².(-4)².(-2)²
= 9.16.4
= 576
