Re: Simplify the following:

Errr, okay - I see now.
Thank you Bobbym.

Please is it possible in the world of logarithm to have different bases at the same time? Like the following;

log5*log2 - the log5 is in base five and the log2 is in base two.

Many thanks!

Re: Simplify the following:

You can always convert to the same base.

Re: Simplify the following:

It means log five base five.
But a log of the same base is equal 1

Re: Simplify the following:

When you say log of 5 to the base 5 you are really saying is what number must 5 be raised up to to get 5. There is only one number that can do that, what is it?

Re: Simplify the following:

How about  log of 2 to the base 2?

Re: Simplify the following:

But you did not talk of the log2 base two.

The log5 base five is multiplying the log2 base two.

Re: Simplify the following:

Oh, did not see your new post. Tony's remark is for the one we  solved.

How about if the log of 5 had base 2 and the log of 2 had base 3, what would have been the answer?

To get the numerical answer would best be done with a calculator.

Unfortunately, the calculator I am using does not have base 3 and the rest, but only base 10

Re: Simplify the following:

You would be solving 2^x = 5 and 3^y = 2.

Re: Simplify the following:

I think there is no number that 2 would raise to give 5,  on the other hand,  there is no number that 3 would raise to give 2

Re: Simplify the following:

There is no whole number but there is definitely numbers that do that.
