Mohon dibantu ya aaaaaa

Kelas 10 Matematika
Bab Logaritma

^ = pangkat

3 . 2^(4x) + 2^(2x) - 10 = 0

2^(2x) = p

3p² + p - 10 = 0
(3p - 5) (p + 2) = 0
3p - 5 = 0
3p = 5
p = 5/3
2^2x = 5/3
²log (5/3) = 2x
²log 5 - ²log 3 = 2x
x = 1/2 . (²log 5 - ²log 3)

p + 2 = 0
p = -2
2^2x = -2 (tidak memenuhi)
