.
8 ⁴log² 3x = 2 ⁴log 9x² + 3
8 ⁴log² 3x - 2 ⁴log (3x)² - 3 = 0
8 ⁴log² 3x - 4 ⁴log 3x - 3 = 0

⁴log 3x1 + ⁴log 3x2 = -b/a = 4/8 = 1/2
⁴log (3x1 × 3x2) = ⁴log 4^(1/2)
9 x1x2 = 4^1/2 = 2
1/(x1x2) = 9/2

(1/(x1x2))² = (9/2)² = 81/4 ✔

8 (⁴log² (3x)) - 2. (⁴log (9x²) - 3= 0

8 (⁴log² (3x)) - 2. (⁴log (3x)² - 3= 0

8 (⁴log² (3x)) - 4. (⁴log (3x) - 3= 0

⁴log (x) = a

8a² - 4. a - 3= 0

a1 + a2 = -(-4) /(8) = 1/2

⁴log (3x1) + ⁴log (3x2) = 1/2

⁴log ( 9.x1. x2) = 1/2

9. x1 x2 = 4^(1/2) = 2

x1. x2 = 2/9

1/(x1. x2) = 9/2
