Himpunan penyelesaian persamaan logaritma 8log (x pangkat 2 + x) = 1/3 adalah...

8log(x²+x)=1/3

x²+x = ∛8
x²+x = 2
x²+x-2 = 0
(x + 2)(x - 1) = 0
x = -2
x = 1

HP = {-2, 1}

⁸log (x^2 + x) = 1/3
⁸log (x^2 + x) = ⁸log8^1/3 --------------->> (coret "⁸log")
x^2 + x = 8^1/3
x^2 + x = ∛8
x^2 + x = 2
x^2 + x - 2 = 0
(x + 2)(x - 1) = 0
x = -2 atau x = 1

Hp = {-2, 1}
