Question 169726
{{{matrix(1,3,4^(-x), "=", x^(1/2))}}} 
If you may please show the steps.
<pre><font size = 4 color = "indigo"><b>
Sorry, there is no algebraic method to 
solve an equation in which the variable 
appears both in an exponent and also in 
a non-exponent.
 
The solution can only be approximated by 
iterative or series solutions, or by a
graphing calculator.

The answer by graphing calculator is:

{{{x=0.36424988978365}}}

So there are no steps to show, unless 
you want to know how I did it on my
TI-84.  If so, post again asking how.
