I have made the amendment- thank you

I have bracket

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?

Please, help.

I don't understand the question.

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

This is it;

log(x^2 + 1) - 2logx = 1

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?

Ok. Let me put this

Log(x-3) - logx = 2.

Is negative one (-1) the correct answer?

Good!

Thanks bobym - I will post problems.

Big thanks!

Again;

x = 10/log16

correct?

like this;

xlog16 = 10

No, the original is log16^x.

xlog16 = log10

xlog16 = 1

x = 1/log16

Correct?

Thanks! Bobbym

I am now getting logarithm better.

See;

solve for x in, log16^x.

log16^x = 10

xlog16 = log10

x = log10/log16

correct?

I think your methods are good concerning the simplification of like terms in logs. Thanks for answering.

Look it if it is good

log16^-x = log2 + log7

-xlog16 = log14

x= -log14/log16

Is it good?

Still I haven't come across the tutor - but I will definitely meet him.

My one question is - when do one take antilogs of both sides of an equation?

I am away from the tutor now - but I shall tell him later

Wow!

I confronted a math tutor - but he claimed the answer 1/3 or -1/3 is correct - now I Could realise that your method is good. Please I want the tutor to see for himself your steps because he was insisting that the books' answer is correct

Thanks bobbym

Yes that's the problem - I copied it correctly.

When you plug in your answers does it give 1?

No, it doesn't give 1/3

It is negative or positive 1/3 in the book as an answer. When I get to the house I will punch them in the calculator and see if it really gives negative or positive 1/3.

Yes I see now

It seems I am not getting you
