Dengan metode pemfakoran. Untuk maka: 15.625 3 15.625 = = = = = 5 × 5 × 5 × 5 × 5 × 5 5 3 × 5 3 3 5 3 × 5 3 5 × 5 25 Untuk Maka: 8.000 3 8.000 = = = = = = 2 × 2 × 2 × 2 × 2 × 2 × 5 × 5 × 5 2 3 × 2 3 × 5 3 3 2 3 × 2 3 × 5 3 2 × 2 × 5 4 × 5 20 Jadi, .

Dengan metode pemfakoran.

Untuk cube root of 15.625 end root

table row cell 15.625 divided by 5 equals 3.125 end cell row cell 3.125 divided by 5 equals 625 end cell row cell 625 divided by 5 equals 125 end cell row cell 125 divided by 5 equals 25 end cell row cell 25 divided by 5 equals 5 end cell row cell 5 divided by 5 equals 1 end cell end table

maka:

$15.625 3 15.625 = = = = = 5 \times 5 \times 5 \times 5 \times 5 \times 5 5^{3} \times 5^{3} 3 5^{3} \times 5^{3} 5 \times 5 25$

Untuk cube root of 8.000 end root

Maka:

$8.000 3 8.000 = = = = = = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 5 \times 5 \times 5 2^{3} \times 2^{3} \times 5^{3} 3 2^{3} \times 2^{3} \times 5^{3} 2 \times 2 \times 5 4 \times 5 20$

table attributes columnalign right center left columnspacing 0px end attributes row cell cube root of 15.625 end root minus cube root of 8.000 end root end cell equals cell 25 minus 20 end cell row blank equals 5 end table

Jadi, .
