The other tutor's answer is wrong.
Apparently, you're an electronics student who uses i for current, and
therefore has to use j for √-1.
Sorry, I thought you wanted jj and worked that out. I'll redo it
and put the results here later. It's actually 4.810477381. But
here is
Now to continue we must find an expression for ln(j)
Euler's equation is
Substitute
Therefore since
then
Now we go back to where we were:
= 0.2078795764

I'm the same person as Edwin McCravy above.
Let's simplify
So we have
So we find
Now to continue we must find an expression for ln(j)
Euler's equation is
Substitute
Therefore since
then
Now we go back to :
Now we go back to
