bentuk pangkat
1³ = 1
2³ = 8
3³ = 27
...
7³ = 343
³√19683 = ab
b → lihat angka satuan → 19683
satuan 3 → 7³
b = 7
a → lihat 19
a³ < 19
cari pangkat 3 yg mendekati 19
2³ < 19
a = 2
•
√1296 = dc
c → lihat satuan 1296
bilangan kuadrat dg satuan 6 → 6²
c = 6
cek 1296
1296 > 35²
1296 > 1225
maka dc > 35
dc = 36
∴
³√19683 × 4² + √1296 / 3²
= 27 × 16 + 36/9
= 432 + 4
= 436
