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!

You can always convert to the same base.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.

Please I wish you solve and that I learn:-)

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

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?

How about log of 2 to the base 2?

But you did not talk of the log2 base two.
The log5 base five is multiplying the log2 base two.

How about log of 2 to the base 2?
It is also 1.

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

I see, it can not be solved

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

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

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

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