Question

calcule as potências a) (3\4)elevado a -2 b)2 elevado a -1 c)(-7\2) elevado a -3 d)(-5\4) elevado a -3 e)(-6) elevado a -2 f)(-2\3)elevado a -4 g)10 elevado a -3 h)(1\9) elevado a -2 i)(5\7) elevado a -2

Answer 1

a) (3/4)^-2= 16/9
b)2^-1= 1/2
c) (-7/2)^-3= (-8/343)
d)(-5/4)^-3= (-64/125)
e)(-6)^-2= 1/36
f)(-2/3)^-4= 81/16
g)10^-3=0,01
h)(1/9)^-2= (81/1)
i)(5/7)^-2= (49/25)
