RRAM conversions

[Johnmoon]

Hello a little help is needed please.
So each time I try and solve this problem I end up with either 64/n^2 or 16/n^2 and either way it turns out to be wrong. Please help with by showing your work and answers just so I can confirm it myself. Thank you.

… Please help [by] showing your work and answers …

It helps volunteer tutors, when students show their work and thoughts, instead. Can you do that?

Please also read the forum's submission guidelines. Thank you!

Rather than seeing my way of doing it, don't you think that it would be better if we do it your way? The only way to do it your way correctly is if we see your work.
