Question

MATEMATIKA MINAT
-LOGARITMA

Answer 1

A) ˣlog 25 = 2
ˣlog 25 = 2
       25 = x²
       5² = x²
x = 5

c) ²log (x - 3) + ² log (x - 2) = 1
² log (x - 3) + ² log (x - 2) = 1
² log (x - 3)(x - 2) = ² log 2
(x - 3)(x - 2) = 2
x² - 5x + 6 = 2
x² - 5x + 6 - 2 = 0
x² - 5x + 4 = 0
(x - 4)(x - 1) = 0
x₁ = 4
x₂ = 1

yang lain dicoba ya biar bisa
