1.4×=64 2.16×+²=64²×-1 3.25×-²=3125 tolong pakai cara

Mapel : Matematika
Kelas : X SMA
Materi : Persamaan Eksponen

Pembahasan :
4^x = 64
4^x = 4³
x = 3

Hp : {3}

————————————————
16^(x + 2) = 64^(2x - 1)
4^(2x + 4) = 4^(6x - 3)
2x + 4 = 6x - 3
6x - 2x = 4 + 3
4x = 7
x = 7/4

Hp : {7/4}

————————————————
25^(x - 2) = 3125
5^(2x - 4) = 5⁵
2x - 4 = 5
2x = 9
x = 9/2

Hp : {9/2}
