Question

Persamaan tersebut memiliki akar x1 dan x2, tentukan nilai x1x2

Tolong ya aku ga ketemu :)

Answer 1

Verified answer

Jawab

²log x²/4 /²log x  + ²log 4x  = 4/ (²log x)
misal ²log x = a
x1x2 = 2⁻⁴

Answer 2

Verified answer

²log (x/2)²/²log x + ²log 4x = 4/²log x
²log (x/2)² + (²log 4 + ²log x)²log x - 4 = 0
2.²log x - ²log 4 + 2.²log x + ²log² x - 4 = 0
²log² x + 4.²log x - 6 = 0

²log x1 + ²log x2 = -b/a = -4
²log (x1x2) = -4
x1 . x2 = 2^-4
