HI! need to solve this logarithmic equation in my casio:
A= 0,5 / ln (A x 5)
How do i get the valour of A? I've tried to use the option "Solve" and i didn't succeed.
GratZ!

Rearrange the equation and use the solver:
A=1/2ln(5A)
2Aln(5A)=1
Go to Equation menu and choose the solver (F3)
Input 2xln(5x)=1
Press solve with initial x=0
The answer is x=0.5216014149
