a$.$ Solve using the periodic interest rate formula $i=(\frac{FV}{PV}{)}^{(\frac{1}{n})}-1.$

Find $i,$ when $PV=$$$3,300,FV=3,580\mathrm{.}85,n=8$

$i=$

Round to four decimal places

b$.$ Solve using the equivalent interest rate formula $i_2=(1+i_1{)}^{(\frac{m_1}{m_2})}-1$

Find $i_2,$ when $i_1=\frac{0\mathrm{.}092}{4},m_1=4,m_2=1$

$i_2=$

Round to four decimal places
