# Write yloga(x) - zIn(x^2) -12logb(X)? as a single log base e? watch

1. need Help???
2. do you know the three log laws and the law to change base?

log(a) of x + log(a) of y = log(a) of xy
log(a) of x - log(a) of y = log(a) of x/y
n [log(a) of x] = log(a) of (x^n)

And change of base,

log(a) of x = [log(b) of x]/[log(b) of a]

Using these, you can solve that.
3. I know the rules, laws wotever but idon't know how to apply it in the context of the question

4. Now use to tidy it up. I'd do it, but I've got to go.
