Question 466402
here's how it works:
your equation is:
9 log w + 4 log z - log (x - 5)
you have 3 basic concepts working here:
concept number 1:
log (a^b) = b*log(a)
concept number 2:
log (a * b) = log(a) + log(b)
concept number 3:
log (a / b) = log(a) - log(b)
using these concept your equation will be transformed as follows:
9 log w + 4 log z - log (x - 5)
using concept 1, you get:
log(w^9) + log(z^4) - log(x - 5)
working from left to right:
using concept 2, you get:
log(w^9 * z^4) - log(x - 5)
using concept 3, you get:
log( (w^9 * z^4) / (x - 5) )
This looks a lot like it matches selection C) log w^9*z^4/x-5
