Answer:

(Véase la explicación para mayores detalles/See the explanation for further details)

Step-by-step explanation:

a) Tres al cubo (Three to cube):

$x = 3 \times 3 \times 3$

$x = 3^{3}$

$x = 27$

b) Seis al cubo (Six to cube):

$x = 6 \times 6 \times 6$

$x = 6^{3}$

$x = 216$

c) Cinco al cuadrado (Five squared):

$x = 5 \times 5$

$x = 5^{2}$

$x = 25$

d) Ocho al cuadrado (Eight squared):

$x = 8 \times 8$

$x = 8^{2}$

$x = 64$

e) Dos a la quinta (Two to five):

$x = 2 \times 2 \times 2 \times 2 \times 2$

$x = 2^{5}$

$x = 32$

f) Diez a la cuarta (Ten to four):

$x = 10\times 10 \times 10 \times 10$

$x = 10^{4}$

$x = 10000$
