how to complete this

Answer:
[tex]m^{4}[/tex] [tex]n^{5}[/tex]
Step-by-step explanation:
using the rule of exponents
[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex]
[tex]\frac{m^8n^6}{m^4n}[/tex]
= [tex]\frac{m^{8} }{m^{4} }[/tex] × [tex]\frac{n^{6} }{n^{1} }[/tex]
= [tex]m^{(8-4)}[/tex] × [tex]n^{(6-1)}[/tex]
= [tex]m^{4}[/tex] [tex]n^{5}[/tex]
