Question

URGENTEMENTE ! ALGUÉM ME AJUDAAA !!!! :-(

(1/3)^ x+1= (1/243)^4x-1

Answer 1

Explicação passo-a-passo:

1. Vamos decompor as bases:

(1/3)^x+1=(1/3^5)^4x-1

(1/3)^x+1=(1/3)^5(4x-1)

(1/3)^x+1=(1/3)^20x-5

2. Mantemos as bases, e igualamos os expoentes:

x+1=20x-5

x-20x=-5-1

-19x=-6

x=6/19
