Jawaban no. 2 adalah (1/2,8)
Jawaban no. 2
(⁴logx)² - ²log√x - 3/4 = 0
(2²logx)² - ²logx½ - 3/4 = 0
[½*²logx)² - ½*²logx - 3/4 = 0
²log²x/4 - ²logx/2 - 3/4 = 0
²log²x - 2²logx - 3 = 0
(²logx+1)(²logx-3) = 0
Solusi 1 :
²logx = -1
x = 2^-1
x = ½
Solusi 2 :
²logx = 3
x = 2³
x = 8
Jadi, nilai x yang memenuhi adalag ½ atau 8
