Hi!

My name is Cleo, I'm 19 years old and I am stuck on this little problem here. If anyone could help me, that would be absolutely wonderful.

I started with this:

111 = 17 + (13^(1/x)-1)*((550-17): (420^(1/x)-1))

and rewrote it to

533*13^(1/x) = 94*420^(1/x) + 439

But now I'm a little lost... How do I find my x?

Thanks in advance for your help!
