27 pangkat x+2 = 9 pangkat 2x-1

27^(x + 2) = 9^(2x – 1)

(3³)^(x + 2) = (3²)^(2x – 1)

3 (x + 2) = 2 (2x – 1)

3x + 6 = 4x – 2

3x – 4x = -2 – 6

-x = -8

x = 8

27^ x+2 = 9^ 2x-1

(3³)^ x+2 = (3²)^ 2x-1

3^ 3x+6 = 3^ 4x-2

3x + 6 = 4x – 2

3x – 4x = -2 – 6

-x = – 8

x = -8/-1

x = 8

Semoga membantu 🙂
