Jawabkan cepet ya pake cara

$frac{ p^{5} q^{-2}r }{ p^{2} q^{-1} r^{3} } = frac{ p^{5} q r }{ p^{2} q^{2} r^{3} } = p^{5-2} q^{1-2} r^{1-3} = p^{3} q^{-1} r^{-2} = frac{ p^{3} }{ q^{} r^{2} }$

jawaban e

$( frac{{p}^{2} {q}^{ - 1} {r}^{3} }{ {p}^{5} {q}^{ - 2} r } )^{ - 1} = : frac{ {p}^{ - 2} {q}^{1} {r}^{ - 3} }{ {p}^{5} {q}^{2} {r}^{ - 1} } \ = {p}^{ - 2 - ( - 5)} {q}^{1 - 2} {r}^{ - 3 - ( - 1)} \ = {p}^{3} {q}^{ - 1} {r}^{ - 2} \ = frac{ {p}^{3} }{q {r}^{2} }$
satu dulu, semoga membantu
