What is the quotient startfraction 15 p superscript negative 4 baseline q superscript negative 6 baseline over negative 20 p superscript negative 12 baseline q superscript negative 3 baseline endfraction in simplified form? assume p not-equals 0, q not-equals 0.

answer
negative startfraction 3 p superscript 8 baseline over 4 q cubed endfraction
negative startfraction 3 over 4 p superscript 16 baseline q superscript 9 baseline endfraction
negative startfraction p superscript 8 baseline over 5 q cubed endfraction
negative startfraction 1 over 5 p superscript 16 baseline q superscript 9 baseline endfraction
