1. Calcule o valor das potências a seguir. a) 12^2= b) (-15)^2= C) (-4)^3= d) (-(2)/(3))^4= e) 248^1= f) 739^circ = g) 0^524= h) (-8)^-2= i) (-0,5)^-3= j) (-0,1)^-8= k) -15^-2=

a) $$12^{2} = 144$$
b) $$(-15)^{2} = 225$$
c) $$(-4)^{3} = -64$$
d) $$(-\frac {2}{3})^{4} = \frac{16}{81}$$
e) $$248^{1} = 248$$
f) $$739^{\circ } = 739$$
g) $$0^{524} = 0$$
h) $$(-8)^{-2} = \frac{1}{64}$$
i) $$(-0,5)^{-3} = -8$$
j) $$(-0,1)^{-8} = 100000000$$
k) $$-15^{-2} = -\frac{1}{225}$$
