Solve the logarithmic equation. Be sure to reject any value that is not in the domain of the original logarithmic expressions. Give the exact answer.

ln sqrt x+6 = 9 i got {e^9-6}

log (x + 4) = log (5x - 5)

i got: 9/4

log (x + 30) - log 2 = log (3x + 2)

i got: {58}

**drwls**, Saturday, October 27, 2007 at 2:06amPlease limit yourself to one question per post, and show your work

log (x + 4) = log (5x - 5)

As long as the bases of both logs are the same,

x + 4 = 5x - 5

4x = 9

x = 9/4

=======================

log (x + 30) - log 2 = log (3x + 2)

(x+30)/2 = (3x+2)

x + 30 = 6x + 4

5x = 26

x = 5.2
