Question

Resolva as equações exponenciaiis

Answer 1

Resposta:

a= x=1

b= x=1

c= x=0

Explicação passo-a-passo:

a= (5/3)^3x-1=25/9

(5/3)^3x-1=(5/3)^2

3x-1=2

3x=2+1

3x=3

x=3/3

x=1

b= (8/27)^2x=64/729

(8/27)^2x=(8/27)^2

2x=2

x=2/2

x=1

c=(1/1024)^x/2=1

(1/1024)^x/2=(1/1024)^0

x/2=0

x=0×2

x=0
