∛8 + √16 - ∛512 + √49 - ∛64 = .......
∛216 + √25 - √36 = ......![]()
∛8 + √16 - ∛512 + √49 - ∛64 = .......
∛216 + √25 - √36 = ......
Penjelasan dengan langkah-langkah:
∛8 + √16 - ∛512 + √49 - ∛64
= 2 + 4 – 8 + 7 – 4
= 6 – 1 – 4
= 1
∛216 + √25 - √36
= 6 + 5 – 6
= 5
⏩ Penyelesaian soal:
Diketahui:
- ∛8 + √16 - ∛512 + √49 - ∛64
- ³√216 + √25 - √36
Ditanya:
- Hasil
Jawab:
= ³√8 + √16 - ∛512 + √49 - ∛64
= ³√2.2.2 + √4.4 - ³√8.8.8 + √7.7 - ³√4.4.4
= ³√2³ + √4² - ³√8³ + √7² - ³√4³
= 2 + 4 - 8 + 7 - 4
= 6 - 8 + 7 - 4
= -2 + 7 - 4
= 5 - 4
= 1
= ³√216 + √25 - √36
= ³√6.6.6 + √5.5 - √6.6
= ³√6³ + √5² - √6²
= 6 + 5 - 6
= 11 - 6
= 5
