Ingat sifat umum dari eksponen, bahwa jika basis  dikali basis yang sama, maka basis itu pangkatnya dijumlahkan. a^{2}.a^{2}=a^{(2+2)}=a^{4}
2.) (\frac{-2p}{q})^{3}.(-q)^{4}.\frac{2}{5}p^{2}
=> \frac{-8p^{3}}{q^{3}}.q^{4}.\frac{2p^{2}}{5}
=> \frac{-16p^{3+2}}{5q^{3-4}}=\frac{-16p^{5}}{5q^{-1}}=-\frac{16}{5}p^{5}q
4.) (a.b.c)^{4}.\frac{3}{(b.c)^{3}}.\frac{b^{3}}{27a^{5}}
=> a^{4}.b^{4}.c^{4}.\frac{3}{b^{3}.c^{3}}.\frac{b^{3}}{3^{3}.a^{5}}
=> a^{4-5}.b^{4+3-3}.c^{4-3}.3^{1-3}
=> \frac{b^{4}c}{9a}
6.) \frac{1}{x^{2}y}:\frac{2x}{3y^{2}}.\frac{5}{3x}.(4y)^{2}
=> \frac{1}{x^{2}y}.\frac{3y^{2}}{2x}.\frac{5}{3x}.16y^{2}
=> \frac{1}{x^{2}y}.\frac{y^{2}}{x}.\frac{1}{x}.y^{2}.\frac{3}{2}.\frac{5}{3}.16
=> x^{-2-1-1}.y^{2+2-1}.40
=> \frac{40y^{3}}{x^{4}}
