Question

1 . log(2x-1) + log(x+3) = 1 + log 3
2. log log (x+3) + log2 = log log 16x
tolong cepat di jawab ya

Answer 1

1. log (2x - 1) + log (x + 3) = 1 + log 3
 log (2x - 1)(x + 3) = log 10 + log 3
log 2x² + 5x - 3 = log 30
2x² + 5x - 3 = 30
2x² +5x - 33 = 0
(2x + 11)(x - 3) = 0
2x + 11 = 0 atau x - 3 = 0
x = -11/2 atau x = 3
