Answer:
8. [tex]\frac{8r^{2} }{q^{2} }[/tex]
10. [tex]12x^{-1} y^{6} z[/tex]
Step-by-step explanation:
8. [tex]\frac{16p^{6}qr^{8} }{2(p^{2}qr^{2})^{3} }[/tex] = [tex]\frac{16p^{6}qr^{8} }{2p^{6}q^{3}r^{6} }[/tex]= [tex]\frac{8r^{2} }{q^{2} }[/tex]
10. [tex]4x^{2} y[/tex] . 3 [tex](-2x^{4} y)^{0}[/tex] . [tex]x^{-3} y^{5} z[/tex] = [tex]4x^{2}y[/tex] . [tex]3(1)[/tex] . [tex]\\x^{-3} y^{5}z[/tex] = [tex]\\12x^{-1}yx^{6}z[/tex]
