17³ + 18³ = …
- 17³ = 17 × 17 × 17 = 289 × 17 = 4.913
- 18³ = 18 × 18 × 18 = 324 × 18 = 5.832
- 4.913 + 5.832 = 10.745
18³ × 21² – 20³ = …
- 18³ = 18 × 18 × 18 = 324 × 18 = 5.832
- 21² = 21 × 21 = 441
- 20³ = 20 × 20 × 20 = 400 × 20= 8.000
- (5.832 × 441) – 8.000
- = 2.571.912 – 8.000
- = 2.563.912
17⁴ – 18⁴ = …
- 17⁴ = 17 × 17 × 17 × 17 = 83.521
- 18⁴ = 18 × 18 × 18 × 18 = 104.976
- 83.521 – 104.976 = -21.455
Jawaban:
pertanyan :
17³ + 18³ =
18³ x 21² – 20³ =
17⁴ – 18⁴ =
jawaban :
no 1
pertama² kita kalikan pangkatnya lalu gabungkan hasilnya
17 × 17 × 17 = 4.913
18 × 18 × 18 = 5.832
4.913 + 5.832 = 10.745
no 2
pertama² kita kalikan pangkatnya
18 × 18 × 18 = 5.832
21 × 21 = 441
20 × 20 × 20 = 8.000
lalu kalikan terlebih dahulu
5.832 × 441 = 2.571.912
lalu kurang
2.571.912 – 8.000 = 2.563.912
no 3
pertama² kita kalikan pangkatnya
17 × 17 × 17 × 17 = 83.521
18 × 18 × 18 × 18 = 104.976
lalu kita kurang
83.521 – 104.976 = -21.455
