Question

1. (5p - 2q)³=
2. (m-5)⁴ =

Pkai caranya ya.. pleasee..

Answer 1

Kalau pakai segitiga pascal..
(5p-2q)³ =
1. (5p)³ (-2q)pangkat nol + 3. (5p)² (-2q)pangkat 1 + 3. (5p)pangkat 1 (-2q)² + 1. (5p)pangkat nol (-2q)³=
1. (125p) .1 +3. (25p) (-2q) +3. (5p) (4q) + 1. 1. (-8q)=
125p³-150p²q+60pq-8q³


(m-5)⁴ =
1. (m)⁴ (-5)pangkat nol + 4. (m)³ (-5)pangkat 1 + 6. (m)² (-5)² + 4. (m)pangkat 1 (-5)³ + 1. (m)pangkat 0 (-5)⁴=
1. m⁴. 1+ 4. m³ (-5) + 6. m² (10) + 4. m (-125) +1. 1. (625)=
m⁴-20m³+60m²-500m+625.

Maaf ya kalau salah ^^

Answer 2

1. (5p - 2q)³=5³p³-2³q³                                   = 125p³-8q³
2. (m-5)⁴ = m∧4-5∧4
             = m∧4-625

∧= pangkat
