Why can neither GeoGebra, nor MathWay solve this simple math problem?

Question

$\frac{e^{0.75}}{-0.5^e+10000}$

This doesn't work either:

$\frac{2.72^{0.75}}{-0.5^{2.72}+10000}$

I can even solve it with a calculator.

Answer 1

First of all, $(-0.5)^e$ is not the same as $-0.5^e$.

Secondly, $x^y$ is not well defined (at least not as a real number) if $x < 0$ and $y$ is not an integer.

Answer 2

Mathway refuses to numerically evaluate. Geogebra Does evaluate the expression correctly

e^(.75)/(10000-.5^e)

Gives

a=0

but if you right click on a and go to object properties the value says

0.00021

which agrees with google calculator

Why you would want to evaluate this in geogebra is beyond me
