Oh its calculus? that explains so much :3 im a freshman in highschool so dont bother asking me XD

Answer 22

no, its not calculus. Its compound interest... Another completly different chapter :p

Answer 23

\(u_n = u_0 \left[ \left(1 + \dfrac{1}{a} \right)^a\right]^{rt} \)

and

\(a = \dfrac{N}{r} \)

Since \(a = \dfrac{N}{r} \), replace a with \(\dfrac{N}{r} \) in the equation at the top:

\(u_n = u_0 \left[ \left(1 + \dfrac{1}{ \frac{N}{r} } \right)^{ \frac{N}{r} } \right]^{rt} \)

\(u_n = u_0 \left(1 + \dfrac{r}{N} \right)^{ \frac{N}{r} \cdot rt} \)

\(u_n = u_0 \left(1 + \dfrac{r}{N} \right)^{Nt} \)

I see it now! Thank you so much!!!
