tolong dong bantu jawab besok dikumpulin, aku bener² gak ngerti:'(

Mapel Matematika
Bab Eksponen

1.
3^(3x - 1) = 1
3^(3x - 1) = 3^0
3x - 1 = 0
3x = 1
x = 1/3

2.
2^(3 - x) = 2^(3x - 5)
3 - x = 3x - 5
8 = 4x
x = 2

3.
3^(x - 2) = (1/3)^(x + 2)
3^(x - 2) = 3^(-x - 2)
x - 2 = -x - 2
2x = 0
x = 0

Kalau ada yg kurang jelas bisa ditanyakan kak

Jawaban terlampir pada gambar :)
