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^96}
log (x + 4) = log (5x  5)
i got: 9/4
log (x + 30)  log 2 = log (3x + 2)
i got: {58}

Please 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 
true or false, all rational numbers are integers. Explain
