$(a) P= \frac{A}{e^{rt}} 

(b) e^{rt}= \frac{A}{P} 

ln e^{rt}= ln(\frac{A}{P}), 
rt= ln(\frac{A}{P}), t= \frac{ ln(\frac{A}{P})}{r}, or, t= \frac{ lnA - lnP}{r},

Answer is given below with explanations.

Step-by-step explanation:

$by \: simplifying \: the \: given \: expression \: using \: \\ law \: of \: exponents \: we \: get \\ \frac{15 {x}^{15} {y}^{ - 3} {z}^{4} }{18 {x}^{18} { {y}^{4} {z}^{ - 4} }^{} } \\ = \frac{5 \: {x}^{ - 3} {y}^{ - 7} {z}^{8} }{6} \\ we \: may \: also \: write \: as \\ = \frac{5 {z}^{8} }{6 {x}^{3} {y}^{7} }$

$formulae \: used \ \: : \\ \frac{ {x}^{m} }{ { {x}^{n} }^{} } = {x}^{m - n} \: \: \: and \\ {x}^{ - m} = \frac{1}{ {x}^{m} }$
