pakai cara ya kakak
Tentukan akar pangkat tiga bilangan-bilangan berikut!
Penjelasan dengan langkah-langkah:
³√216
= √6³
= 6^(3/3)
= 6¹
= 6
³√729
= √9³
= 9^(3/3)
= 9¹
= 9
∛2.197
= ∛13³
= 13^(3/3)
= 13¹
= 13
5 × ³√1.331
= 5 × ³√11³
= 5 × 11^(3/3)
= 5 × 11¹
= 5 × 11
= 55
³√125 × ³√3.375
= ³√5³ × ³√15³
= 5^(3/3) × 15^(3/3)
= 5¹ × 15¹
= 5 × 15
= 75
³√5.832 – ³√2.197
= ³√18³ – ³√13³
= 18^(3/3) – 13^(3/3)
= 18¹ – 13¹
= 18 – 13
= 5
³√8.000 : ³√64
= ³√20³ : ³√4³
= 20^(3/3) : 4^(3/3)
= 20 : 4
= 5
7³ – 2³ + ³√216
= (7×7×7) – (2×2×2) + ³√6³
= (49×7) – (4×2) + 6^(3/3)
= 343 – 8 + 6¹
= 343 – 8 + 6
= 335 + 6
= 341
(4 + 8) – ³√729 : ³√27
= 12 – ³√9³ : ³√3³
= 12 – 9^(3/3) : 3^(3/3)
= 12 – 9¹ : 3¹
= 12 – 9 : 3
= 12 – 3
= 9
³√1.728 × ³√125 : ³√64
= ³√12³ × ³√5³ : ³√4³
= 12^(3/3) × 5^(3/3) : 4^(3/3)
= 12¹ × 5¹ : 4¹
= 12 × 5 : 4
= 60 : 4
= 15
