1. Calcule cada uma das potências a seguir: 28 a) 5^375 b) 34 C) (-3)^481 d) -(-3)^48 e) -3^4-81 f) (-1,6)^22,56 g) 7-2 7^-2underline ( ) h) ((2)/(5))^3underline ( ) i) ((2)/(5))^-3 j) (-(3)/(4))^3underline ( ) k) (-(3)/(4))^4 I) ((7)/(8))^0underline ( )

a) $$5^{3} = 125$$
b) 34
c) $$(-3)^{4} = 81$$
d) $$-(-3)^{4} = -81$$
e) $$-3^{4} = -81$$
f) $$(-1,6)^{2} = 2,56$$
g) $$7^{-2} = \frac{1}{49}$$
h) $$(\frac{2}{5})^{3} = \frac{8}{125}$$
i) $$(\frac{2}{5})^{-3} = \frac{125}{8}$$
j) $$(-\frac{3}{4})^{3} = -\frac{27}{64}$$
k) $$(-\frac{3}{4})^{4} = \frac{81}{256}$$
l) $$(\frac{7}{8})^{0} = 1$$
