1) (2m^{2}n^{5})^{2} * (-m^{3}n)^{2}
= 4m^{4}n^{10} * m^{6}n^{2}
= 4m^{10}n^{12}

2) p^{-1/2} (q/p)^{1/2}
= 1/p^{1/2} q^{1/2}/p^{1/2}
= q^{1/2} / p^{1/4}

3) (a^{-1} + b^{-1}) / (a^{-2} + a^{-2})
= (a^{2} + a^{2})/ (a^{1} + b^{1})
= 2a^{2} / (a^{1} + b^{1}

ada pilihan gandanya kah? kalau kgk ada di jawaban / krng sederhana, silahkan komen dibawah :v ↓
