Me ajudaaaaaaaaaaaaaaaaaaaaaaaaaa!
calcule as seguintes potências:
a)5^0
b)(-4\7)¹
c)3-¹
d)(-3)²
e)(2\3)-²
f)(-3\4)-³
g)(1\5)-¹
h)(0,75)-²
g)2^6
i)(-2)^6
j)2^5
calcule as seguintes potências:

d)(-3)²
e)(2\3)-²
f)(-3\4)-³
g)(1\5)-¹
h)(0,75)-²
g)2^6
i)(-2)^6
j)2^5
Lista de comentários
a)5^0 = 1
b)(-4\7)¹ = -4/7
c)3-¹ = 1/3
d)(-3)²= + 9
e)(2\3)-² = (3/2)^2 ==> 9/4
f)(-3\4)-³ (-4/3)^3 ==> 64/27
g)(1\5)-¹ = (5/1)^1 ==> 5
h)(0,75)-² = (75/100)^-2 ==> (100/75)^2 ==> 10000/5625
i)(-2)^6 = +64
j)2^5 = 32
