Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am having trouble getting my head around this:

Can someone explain why

[tex]x^{x}[/tex] = [tex]e^{xlgx}[/tex]

I cannot seem to understand why this is true. I am quite weak when it comes to handling exponentials. I dare say that I am terrified of e!

Also, would this also hold for a static power: so [tex]x^{a}[/tex]

Thanks,

Luca
