Bab Bilangan Pangkat TigaMatematika SD Kelas VI
a³ + b³ x ∛(512) = 1.343
7³ + b³ x 8 = 1.343
b³ x 8 = 1.343 - 343
b³ = 1.000 : 8
b = ∛125
b = 5

Bab Bilangan KubikSekolah Dasar Kelas V
^ itu pangkat
a = 7
a^3 + b^3 × akar kubik 512 = 1343
b^3 = ( 1343 - 7^3 )÷ 8
= ( 1343 - 343 ) ÷ 8
= 1000 ÷ 8
= 125
b = akar kubik dari 125
b = 5
