hasil dari (256)pangkat ¼ + (625)pangkat¾ -(121)pangkat½adalah

(256)^(1/4) + (625)^(3/4) - (121)^(1/2)

= (4^4)^(1/4) + (5^4(^(3/4) - (11^2)^(1/2)

= 4^1 + 5^3 - 11^1

= 4 + 125 - 11

= 118 


Semoga membantu

[tex] {4}^{4( \frac{1}{4} )} + {5}^{4( \frac{3}{4}) } - {11}^{2( \frac{1}{2}) } \\ = 4 + {5}^{3} - 11 \\ = 129 - 11 = 118[/tex]
