The formula A=p(1 + R/100) raised to n
i ned to get only the R t left side an rest to the right..
Plz help
You start off with:
$\displaystyle P\left(1+\frac{R}{100}\right)^n = A$
$\displaystyle \left(1+\frac{R}{100}\right)^n = \frac{A}{P}$
Root both sides by n
$\displaystyle 1+\frac{R}{100} = \sqrt[n]{\frac{A}{P}}$
$\displaystyle \frac{R}{100} = \sqrt[n]{\frac{A}{P}} -1$
$\displaystyle R = 100\sqrt[n]{\frac{A}{P}} -100$
