Log problem...please include some detail so I can do the others

[From: ] [author: ] [Date: 11-04-22] [Hit: ]
..by the way, upper and lower case letters represent different variables.......
log (base 3) X + log (base 3) (x+9) = 5

-
the sum of logs is the log of the product...

log (base 3) X + log (base 3) (x+9) = 5

log [base 3] [x(x + 9)] = 5

x^2 + 9x = 243

x^2 + 9x - 243 = 0

use the quadratic formula...

x = [- 9 ± √(1053)]/2

only the positive root is valid...

check
