Logaritma Ini jawabannya apa kak? Mohon beserta caranya, terimakasih

Bab Logaritma

^ = pangkat

^3log x^(2 + ^3log x) = 15
(2 + ^3log x) (^3log x) = 15
^3log² x + 2 . ^3log x - 15 = 0
a² + 2a - 15 = 0
(a + 5) (a - 3) = 0
a + 5 = 0
a = -5

^3log x = -5
x = 3^-5

a - 3 = 0
a = 3

^3log x = 3
x = 3^3

Hasil kali akar-akar
= 3^(-5) . 3^3
= 3^(-5 + 3)
= 3^(-2)
= 1/9
