Re: Simplify the following:
That makes a difference.
In mathematics, you don't understand things. You just get used to them.

Re: Simplify the following:
Ask the tutor to plug and check his answer.
Yes - have seen the tutor - the tutor gave me a calculator which I plugged 1/3 into the equation and I had 1(one), so it seems his answer is correct. What do you say Bobbym?

Please rewrite the question, I have forgotten which one you are talking about.

Re: Simplify the following:
This is it;
log(x^2 + 1) - 2logx = 1

Re: Simplify the following:
The logs are common or natural?
Also that is not the equation you gave in post #664. In post #664 you gave this equation
log(x+1) - 2logx^2=1
That is the equation I said does not have a root of 1 / 3.
Now you are giving this equation.
This is it;
log(x^2 + 1) - 2logx = 1
They are not the same.

Re: Simplify the following:
Show that
Log x = 1/2logx and hence solve log x + 1/2 = logx
In both cases the LHS is in base 4 and the RHS is in base 2
Thanks

Re: Simplify the following:
Please, help.
I don't understand the question.

Re: Simplify the following:
Hi;
Sorry, I was away pretty much all day. Where are you stuck?
Looks like the first thing you should do is convert those weird logs to the natural log and then you should have no problem.
Do you know how?

Re: Simplify the following:
Hi;
I am given it a try concerning the conversion;
Log x = 1/2log x
so, it will be
log (x) = 1/2log (x)
Is that correct?

Re: Simplify the following:
I can not say. Please bracket the expression.

That is true but it is an extremely complicated and cumbersome way to do the problem.
