Question

Calcule as potências:

a)(-3/4)² b)(+5/4)² c)(-1/2)⁵
d)(-15/8)⁰ e)(-1/3)³ f)(-7/13)¹ g)(+1,7)²
h)(-10)⁵ i)(-1)²⁰⁰ j)(-0,4)³ k)(+2/3)⁴​

Answer 1

Explicação passo-a-passo:

a) (-3/4)²= +9/16

b) (+5/4)²= 25/16

c) (-1/2)^5= - 1/32

d) (-15/8)°= 1

e) (-1/3)³= - 1/27

f) (-7/13)¹= -7/13

g) (+1,7)²= +2,89

h) (-10)^5= - 100000

i) (-1)^200= +1

j) (-0,4)³= - 0,064

k) (+2/3)⁴= 2⁴/3⁴= + 16/81
