(10)Calcule as potências apresentadas a seguir. a) 6^3=underline ( ) b) 70^6=underline ( ) c) ((2)/(3))^3=underline ( ) d) (-3)^2=underline ( )

a) $$6^{3} = 6 \times 6 \times 6 = 216$$

b) $$70^{6} = 70 \times 70 \times 70 \times 70 \times 70 \times 70 = 117649000000$$

c) $$(\frac{2}{3})^{3} = \frac{2}{3} \times \frac{2}{3} \times \frac{2}{3} = \frac{8}{27}$$

d) $$(-3)^{2} = (-3) \times (-3) = 9$$
