Show that the ratio of the accumulated value of $\$1$ invested ta rate i for n periods, to the accumulated value of $\$1$ invested at rate j for n periods, is equal to the accumulated value of 1 invested for mn periods at rate r. Find an expression for r at as a function of i,j and m.
Ans:$(\frac{1+i}{1+j})^{\frac{1}{m}}-1$
