Question

4 log x-6 log (x+2) write the expression as a single logarithm.
a.24 log x/x+2
b.log x^4 (x+2)^6
c.logx(x+2)^24
d.none

Answer 1

Do you remember your logarithm laws?

Answer 2

4logx = log(x^4)
-6log(x+2) = log((x+2)^-6)
so 4logx -6log(x+2) = log(x^4)+log((x+2)^-6) = log(x^4*(x+2)^-6) = log (x^4/(x+2)^6)

Answer 3

that works too ._.
