Ingat aturan pada perpangkatan,

Maka,

a. 5 cubed

table attributes columnalign right center left columnspacing 0px end attributes row cell 5 cubed end cell equals cell 5 cross times 5 cross times 5 end cell row blank equals cell 125 cross times 5 end cell row blank equals 625 end table

b. open parentheses 1 half close parentheses to the power of 4

$table attributes columnalign right center left columnspacing 0px end attributes row cell open parentheses 1 half close parentheses to the power of 4 end cell equals cell 1 to the power of 4 over 2 to the power of 4 end cell row blank equals cell fraction numerator 1 cross times 1 cross times 1 cross times 1 over denominator 2 cross times 2 cross times 2 cross times 2 end fraction end cell row blank equals cell 1 over 16 end cell end table$

c. 3 to the power of negative 3 end exponent

$table attributes columnalign right center left columnspacing 0px end attributes row cell 3 to the power of negative 3 end exponent end cell equals cell 1 over 3 cubed end cell row blank equals cell fraction numerator 1 over denominator 3 cross times 3 cross times 3 end fraction end cell row blank equals cell fraction numerator 1 over denominator 9 cross times 3 end fraction end cell row blank equals cell 1 over 27 end cell end table$

d. negative 2 to the power of 4

e. open parentheses negative 2 close parentheses to the power of 4

Jadi, hasil dari 5 cubed equals 125 , open parentheses 1 half close parentheses to the power of 4 equals 1 over 16 , 3 to the power of negative 3 end exponent equals 1 over 27 , negative 2 to the power of 4 equals negative 16 dan open parentheses negative 2 close parentheses to the power of 4 equals 16 .
