Answer:
x = 2
Step-by-step explanation:
(x² logₓ27) log₉x = x + 4
Use change of base formula.
x² (log 27 / log x) (log x / log 9) = x + 4
Simplify.
x² (log 27 / log 9) = x + 4
x² (log 3³ / log 3²) = x + 4
x² (3 log 3 / (2 log 3)) = x + 4
x² (3 / 2) = x + 4
3x² = 2x + 8
3x² − 2x − 8 = 0
(x − 2) (3x + 4) = 0
x = 2 or -4/3
Since x > 0, x = 2.
(2/3) / (1/9) = x / 1....2/3 day to 1/9 order = x days to 1 order
cross multiply
(1/9)(x) = (2/3)(1)
1/9x = 2/3
x = 2/3 * 9
x = 18/3
x = 6 days <==
