j)(2/7)⁻³ =
k)3⁰ + 3¹ - (-3)⁰ - (-3)¹ =
Me ajudem porfavor

Answer 1

Explicação passo-a-passo:

a)3⁻³ = 1/3³= 1/9

b)(1/3)³ =1/9

c)(2/5)² =4/25

d)(-2)⁴ =1/2⁴= 1/16

e)-2⁴ =-16

f)(-2)⁻² = 1/2²= 1/4

g)2⁻³ + 3⁻² . (1/3)⁻¹ = 1/2³+1/3².3¹= 1/8+1/9.3= 1/8+3/9= 1/8+ 1/3=3+8/24= 11/24

h)(-3)⁻³ =-1/3³=-1/27

i)(5/2)⁻² =2²/5²=4/25

j)(2/7)⁻³ =7³/2³=343/8

k)3⁰ + 3¹ - (-3)⁰ - (-3)¹ =1+3+3= 7

Espero te ajudado :)
