3log2x - 3logx5 + 4 = 0 itu 3 log pangkat 2 x - 3log x pangkat 5 + 4 = 0

³log²x - ³log x^5 + 4 = 0
(³log x)² - 5 . ³log x + 4 = 0
mis ³log x = a

a² - 5a + 4 = 0
(a - 4)(a - 1) = 0

a = 4
³log x = 4
x = 3⁴ = 81

a = 1
³log x = 1
x = 3¹ = 3

Hp = { 3 , 81 }

==Jawaban==

³log²x - ³logx⁵ + 4 = 0
³log²x - 5.³logx + 4 = 0

Kita pakai permisalan yaa,,
³logx = p

Jadi,,,,,
p² - 5p + 4 = 0
(p - 1)(p - 4) = 0

Kemudian masukkan nilai "p" nya yaa,
p - 1 = 0
³logx - 1 = 0
³logx = 1
³logx = ³log3¹ 
x = 3¹
x = 3

p - 4 = 0
³logx - 4 = 0
³logx = 4
³logx = ³log3⁴
x = 3⁴
x = 81

Hp = {3 dan 81}
