Dear Student, -3p4q-324p-5q7=(-3)2(p)8(q)-6×4×(p)-5(q)7 =9×p8×q-6×4×p-5×q7=36×p3×q=36p3q Regards

Pls do it fast

Dear Student,

{(- 3 p^{4} q^{- 3})}^{2} (4 p^{- 5} q^{7}) = {(- 3)}^{2} {(p)}^{8} {(q)}^{- 6} \times 4 \times {(p)}^{- 5} {(q)}^{7} = 9 \times p^{8} \times q^{- 6} \times 4 \times p^{- 5} \times q^{7} = 36 \times p^{3} \times q = 36 p^{3} q
