But what has that got to do with Excel?

This is a paper exercise. Start with

A=P(1+i/2)^n*2 = A/P=(1+i/2)^n*2 = A/2P=(1+i/2)^n = (A/2P)^(1/n)=1+i/2
etc

Just follow the same steps for the second equation.

Trying to do a school project and need to find i in the formula
A=P(1+i/2)^n*2. Also in a different question I need to find n in the
formula A=P(1+i/12)^n*12
