Nilai x yang memenuhi ²log²(x+1)- 2 ²log (x+1)-8=0 adalah?
²log²(x + 1) – 2 ²log(x + 1) – 8 = 0
(²log(x+1) – 4)(²log(x + 1) + 2) = 0
²log(x + 1) – 4 = 0 atau ²log (x + 1) + 2 = 0
²log(x + 1) = 4 ²log (x + 1) = -2
x + 1 = 16 x + 1 = 1/4
x = 16 – 1 x = 1/4 – 1
x = 15 x = 1/4 – 4/4
x = -3/4
.
Maaf jika terdapat ketidaktelitian… ^^
