Question

Solve for n 50 points

a=p(1+r/n)^rn

Answer 1

`n = \frac{r}{\sqrt[nt]{(a)/(p)} -1 }`

Explanation:

`a=p(1+(r)/(n) )^(nt)`

`(a)/(p) =(1+(r)/(n) )^(nt)`

`\sqrt[nt]{(a)/(p)} =(1+(r)/(n) )`

`\sqrt[nt]{(a)/(p)} -1 =((r)/(n) )`

`n = \frac{r}{\sqrt[nt]{(a)/(p)} -1 }`

[ Do not confuse, as there are 2 n's, one in subject and another as power. We can never make the power or in a root, the subject. In order to solve for n, we have to make the character "n", the subject. ]
