    Please help solve for a variable

    Here is my equation

    a = [P((1 + r)^n)r]/[(1 + r)^n - 1]

    I need to solve for "r" and I have absolutely no clue. I can not simply down to r, I keep getting stuck.

    Thanks in advance, any help would be appreciated.

    do you mean A = \frac {P[(1 + r)^n]r}{(1 + r)^n -1}?

    hmmm. it's very hard to solve that for r. are you sure (n - 1) isn't the power of (1 + r) in the denominator?
