please jawab skarang yaaaa, pkek cara

Yg kliatan aja ya... :)

3][
3^(3x - 5) = ³√9^(2x + 5)
3x - 5 = 2/3 (2x + 5)
Kali silang
9x - 15 = 4x + 10
5x = 25
x = 5

4][
(3^(x-1))^2 × (3^-1/2)^-1 × 3^3x / (3^(x - 4) × 3^-x)
= 3^(2x - 2 + 1/2 + 3x) / 3^(x - 4 - x)
= 3^(5x - 3/2 - (-4))
= 3^(5x + 5/2)

nomor 4................
