plis bantu kerjakan yang ikhlas yaa
1. 6³ - 3³ = (6 × 6 × 6) - (3 × 3 × 3)
= (36 × 6) - (9 × 3)
= 216 - 27
= 189
2. 15³ = 15 × 15 × 15
= 225 × 15
= 3.375
3. Diketahui: V = 49.000 dm³
l = 14 dm
t = 14 dm
Diranya: Panjang?
Jawab: p = V ÷ (l × t)
p = 49.000 ÷ (14 × 14)
= 49.000 ÷ 196
= 250
4. ³√125 = 5
= 5³
= 5 × 5 × 5
= 25 × 5
= 125
³√343 = 7
= 7³
= 7 × 7 × 7
= 49 × 7
= 343
