Effective interest rate to nomial

[English101]

Hey,

How do you go from effective interest rate to nomial interest rate.

Cheers.

So I never did this, since this was introduced after I did Further, but just found the formula for nominal to effective interest rate here.
My assumption would be that you could essentially do the opposite operations and receive the effective interest rate from the nominal rate.
This would mean that the equation would be: r = m*[(i_a + 1)^(1/m) - 1]
where everything is defined as the link above.

The formula is on the VCAA formula sheet issued in both exams.
