e(4×x)5=8{x=ln(13(14)×i)ln(e)x=ln((13(14)))ln(e)x=ln((13(14)×i))ln(e)x=ln(13)(4×ln(e))}

 

There you go - it has got 2 real solutions and 2 imaginary solutions.

 

e4x5=8e4x=13ln(e4x)=ln(13)4xln(e)=ln(13)4x=ln(13)x=ln(13)/4

 

that is interesting, I missed out on one of  the answers

Thanks but I already ate far too much tonight.

Don't you know how to make that image smaller?

Can you please Alan ?

I tried to shrink the image, but it appears I can't.

Ok well thanks for the cookie I shall put it aside for later. :)

Perhaps you could find a little gold star for next time (I should be on a diet anyway)

The huge pic is a bit distracting in the middle of a thread but it was a really nice gesture :)
