⁴log²(2x-1) - ⁴log(2x-1)^5 + 6 = 0

Misalkan ⁴log(2x - 1) = a
⁴log²(2x - 1) - ⁴log(2x - 1)⁵ + 6 = 0
a² - 5a + 6 = 0
(a - 2)(a - 3) = 0
a = 2 atau a = 3

Untuk a = 2
⁴log(2x - 1) = 2
⁴log(2x - 1) = ⁴log 4²
2x - 1 = 16
2x = 17
x = 8 1/2

Untuk a = 3
⁴log(2x - 1) = 3
⁴log(2x - 1) = ⁴log 4³
2x - 1 = 64
2x = 65
x = 32 1/2

Jadi x = 8 1/2 atau x = 32 1/2.
