    you meant to say this right? \[\Large A = P\left[ \left(1+\frac{r}{n}\right)^{\frac{1}{c}} \right]^{cnt}\] \[\Large A = 39145\left[ \left(1+\frac{0.03}{12}\right)^{\frac{1}{4}} \right]^{4*12*t}\]

    if you want to evaluate 1.00025^(1/4), make sure you type that in and hit the equal sign don't forget the parenthesis

    I'm guessing #3 wants you to solve for r?

    solve this for r maybe? \[\Large 1+\frac{r}{n} = P\left[ \left(1+\frac{r}{n}\right)^{\frac{1}{c}} \right]^{cnt}\]

    \[a(t)=39,145[(1+\frac{ .003 }{ 12 })^{(1/4)}]\] ^(4)(12)(-45.5)

    39,145[(1.00025)^1/4]^(-2184) -39,145=1^-2184 -39,145=1 39,145

    or you're just trying to evaluate 39,145[(1.00025)^1/4]^(-2184) ?

    i guess just evaluate that cause the question asks to solve for the adjusted intrest rate

    I'm stuck on the fact that they bring in c = 4, but the 'c' terms cancel (when they divide). This problem is just odd. Hmm
