we have that
[tex]2a^{-4} m^{5} [/tex]
Remove the negative exponent by rewriting
[tex] a^{-4} [/tex] as [tex] 1/a^{4} [/tex]
[tex]2(1/a^{4})m^{5} [/tex]
Simplify [tex]2 (1/ a^{4} )[/tex]
Write 2 as a fraction with denominator 1.
[tex](2/1)(1/a^{4} ) m^{5} [/tex]
Multiply [tex](2/1)[/tex] and [tex](1/ a^{4} )[/tex] to get [tex]2/ a^{4} [/tex]
[tex](2 /a^{4}) m^{5} [/tex]
Write m5 as a fraction with denominator 1
[tex](2/ a^{4})( m^{5} /1) [/tex]
Multiply
[tex](2/ a^{4}) [/tex] and [tex]( m^{5}/1) [/tex] to get [tex]2 m^{5} / a^{4}[/tex]
the answer is
[tex]2 m^{5} / a^{4}[/tex]
