Hello all

I have another log problem which I was hoping someone could help me with.

I have the following:-

logY^3 = logx(x+4)^2

I have been told that the above statement is the same as:-

Y^3 = x(x+4)

The bit I don't understand is where does the log go?

What law allows the log to be removed from both sides?

Can anyone help?

Thank you.

(assume base 10 log)
