Matematik Tingkatan 1 Bab 5 Ungkapan Algebra

J Permudahkan setiap pendaraban berulang yang berikut. TP 2 ARAS R
Simplify each of the following repeated multiplication.

Contoh Contoh
j × j × j (k – l) × (k – l) × (k – l) × (k – l)
= j 3 = (k – l) 4

1. n × n × n × n × n × n × n 3. (a + c) × (a + c) × (a + c) × (a + c) × (a + c)
= n 7 = (a + c) 5

2. (–q) × (–q) × (–q) × (–q) × (–q) × (–q) 4. (uv – vw) × (uv – vw) × (uv – vw)
= (–q) 6 = (uv – vw) 3

K Ungkapkan setiap yang berikut dalam bentuk pendaraban berulang. TP 2 ARAS R
Express each of the following in the form of repeated multiplication.

Contoh 1. (2a – bc) 3
(c + 2d) 2 = (2a – bc) × (2a – bc) × (2a – bc)
= (c + 2d) × (c + 2d)

2. (tu + vw) 3 3. (3 – pq)
= (tu + vw) × (tu + vw) × (tu + vw) = (3 – pq) × (3 – pq) × (3 – pq) × (3 – pq)

L Permudahkan setiap yang berikut. TP 2 ARAS R
Simplify each of the following.

Contoh 1. 4r × 5rs
= 4 × r × 5 × r × s
2
2m n × 3mn 2
= 4 × 5 × r × r × s
= 2 × m × m × n × 3 × m × n × n Kembangkan = (4 × 5) × (r × r) × s
= 2 × 3 × m × m × m × n × n × n setiap sebutan = 20r s

= 0.6 × a × a × b × 10 × a × b = 7 × v × w × w × 8 × v × v × w × w
= 0.6 × 10 × a × a × a × b × b = 7 × 8 × v × v × v × w × w × w × w
= (0.6 × 10) × (a × a × a) × (b × b) = (7 × 8) × (v × v × v) × (w × w × w × w)
= 6a b = 56v w 4
