Dengan metode pemfakoran.

Untuk cube root of 4.913 end root   

table row cell 4.913 divided by 17 equals 289 end cell row cell 289 divided by 17 equals 17 end cell row cell 17 divided by 17 equals 1 end cell end table 

Maka:

table attributes columnalign right center left columnspacing 0px end attributes row cell 4.913 end cell equals cell 17 cross times 17 cross times 17 end cell row blank equals cell 17 cubed end cell row cell cube root of 4.913 end root end cell equals cell cube root of 17 cubed end root end cell row blank equals 17 end table 

Untuk cube root of 27.000 end root 

table row cell 27.000 divided by 2 equals 13.500 end cell row cell 13.500 divided by 2 equals 6.750 end cell row cell 6.750 divided by 2 equals 3.375 end cell row cell 3.375 divided by 3 equals 1.125 end cell row cell 1.125 divided by 3 equals 375 end cell row cell 375 divided by 3 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:

table attributes columnalign right center left columnspacing 0px end attributes row cell 27.000 end cell equals cell 2 cross times 2 cross times 2 cross times 3 cross times 3 cross times 3 cross times 5 cross times 5 cross times 5 end cell row blank equals cell 2 cubed cross times 3 cubed cross times 5 cubed end cell row cell cube root of 27.000 end root end cell equals cell cube root of 2 cubed cross times 3 cubed cross times 5 cubed end root end cell row blank equals cell 2 to the power of 3 over 3 end exponent cross times 3 to the power of 3 over 3 end exponent cross times 5 to the power of 3 over 3 end exponent end cell row blank equals cell 2 cross times 3 cross times 5 end cell row blank equals 30 end table 

table attributes columnalign right center left columnspacing 0px end attributes row cell cube root of 4.913 end root plus cube root of 27.000 end root end cell equals cell 17 plus 30 end cell row blank equals 47 end table  

Jadi, table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell cube root of 4.913 end root end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank plus end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell cube root of 27.000 end root end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank equals blank end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank 47 end table.
