Exponential function in terms of logarithms

Click For Summary
SUMMARY

The discussion focuses on expressing the exponential function b^{x} in terms of logarithms. The key transformation is b^{x} = e^{x ln(b)}, which utilizes the natural logarithm. The participant also references the Taylor series expansion of the exponential function, demonstrating the relationship between exponential and logarithmic forms. The discussion concludes with the correct formulation and acknowledges an initial misunderstanding.

Homework Statement


Express [tex]b^{x}[/tex] as a function of logarithms.


Homework Equations


There are a couple of equations in the attempted solution. I can't say if they are actually relevant


The Attempt at a Solution



I've investigated the property
[tex]y = log_{b}(b^{y}),[/tex]
and also
[tex]log_{b}(y) = \frac{log_{k}(y)}{log_{k}(b)}[/tex]

This hasn't help me any.

I got it. It's

[tex]b^{x} = e^{x ln(b)} = b + \frac{x ln(b)}{1!}+ \frac{(x ln(b))^{2}}{2!}+ \frac{(x ln(b))^{3}}{3!}+ \frac{(x ln(b))^{4}}{4!}+...[/tex]
