Bentuk sederhana dari (9p^2q^-3)^4 x (27p^4q^-2)^-3

[tex] {( {9p}^{2} {q}^{ - 3} {)}^{4} } \times {(27 {p}^{4} {q}^{ - 2}) }^{ - 3} \\ = {( {3}^{2}) }^{4}. {p}^{8} . {q}^{ - 12} \times {( {3}^{3}) }^{ - 3} . {p}^{ - 12} . {q}^{6} \\ = \frac{ {3}^{8} . {p}^{8}. {q}^{6} }{ {3}^{9} .{q}^{12}. {p}^{12} } \\ = \frac{1}{3 {p}^{4} {q}^{6} } [/tex]
