tlg cari nilai x thx^^

Logaritma
Kelas X

²log ²log (2ˣ⁺¹ + 3) = 1 + ²log x
²log ²log (2ˣ⁺¹ + 3) = ²log 2 + ²log x
²log ²log (2ˣ⁺¹ + 3) = ²log 2x
²log (2ˣ⁺¹ + 3) = 2x
2ˣ⁺¹ + 3 = 2²ˣ
(2ˣ)² - (2ˣ • 1) - 3 = 0

Misal 2ˣ = a

a² - 2a - 3 = 0
(a - 3)(a + 1) = 0
a = -1 (ditolak) atau a = 3

2ˣ = 3
x = ²log 3
