### Rydberg Formula Derivation and Units for Quiz #1

I was wondering which form of the Rydberg formula will be appropriate for calculations on the quiz.
If the simplified form of $v=R((\frac{1}{n{1}^{2}})-(\frac{1}{n{2}^{2}}))$ is used on the quiz, will we not receive full credit for the work shown in the problem?... If this is the case, can we show the derivation of this form from this equation: $E{n}=-\frac{hR}{n^2}$ and then plug in the values into: $v=R((\frac{1}{n{1}^{2}})-(\frac{1}{n{2}^{2}}))$ to be able to receive full credit?

What would you guys say is the most recommended method for the simplest and less error-likely answer?

I was told only to use the equation $E{n}=-\frac{hR}{n^2}$. However, you can use the simplified form as long as you show how you derived it from the original equation. You should use the simplified form if you are confident in your calculations, otherwise I would suggest using the original $E{n}=-\frac{hR}{n^2}$ for a less error-likely answer.
