solve the equation
loga(x5) loga (x+9)=loga(x7)loga(x+9)
all a's are lower
please show work

collect logs
log((x5)/(x+9)) = log((x7)/(x+9))
(x5)/(x+9) = (x7)/(x9)
assuming x ≠ 9,
x5 = x7
5 = 7
no solution  typo?
even easier, add log(x+9) to both sides to get
log(x5) = log(x7)
x5 = x7
no solution

Can someone show how to this question. Loga(x+3) + Loga(x3) = 3 I don't know if I'm typing this correctly the a is the base. So, I'm thinking, Loga((x+3)(x3)) = 3 (x+3)(x3) = 3^a x^2  9 = 3^a, x^2 = 3^a + 9 x = sqrt(3^a + 9) but …
