You can put this solution on YOUR website!
matrix%281%2C3%2C4%5E%28-x%29%2C+%22=%22%2C+x%5E%281%2F2%29%29
If you may please show the steps.

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.
