exp(log10(x))=y x=?

[Ataner]

Could you help me? How can I transform this? Thanks!

exp(log10(x))=y x=?

 

[tkhunny]

Have you considered introducing the logarithm?

[math]ln(log_{10}(x)) = ln(y)[/math]
Now what?

I have to type in an equation to calculate x
by exp(log10(x))=23*y-4.45 equation.

 

[skeeter]

would this be the equation you want solved for x?

[MATH]e^{\log_{10}{x}} = 23y - 4.45[/MATH]

You might consider rewriting the base-ten log using the change of base formula. Then you can solve by taking a natural log.

Have you considered introducing the logarithm?

[math]ln(log_{10}(x)) = ln(y)[/math]

I think you meant to have an exp in there.

yes

we have a softwere which give me a regression equation, exactly:
exp(log10(x))=23*y-4.45
and I have to type in an equation for an other dataset to calculate x=......

example:
log10(x)=y+3 then I can type in x=10^(y+3), and I get x
but I don't know how to transfer everything to the right side if we have exp(log10)
-> exp(log10(x))=23*y-4.45
to get x=......
I don't want to have exp(log10) on the left side, I want them somehow to move to the right side and get an equation only for x
I'm sorry about my English...

Use:

log_e(x) = ln(x)​

log₁₀(x) = log₁₀(e) * ln(x)​

and:

x = e^ln(x)​

continue......

That equality you wrote does not follow from the problem that the OP posted.

In response #6, DrP addressed your concern. Wake up Jomo....

An error like that needs to be repeated. You really do act as a moderator--excuse me, super moderator.

 

[Ataner]

Thanks a lot!

Yeah....and don't you forget that!!!
