Answer:

The expression can be simplified as [tex]17\frac{1}{2}[/tex]m·n

Step-by-step explanation:

Given the expression:

(m·5/2·n·7/2)·2

[tex](m\frac{5}{2} n\frac{7}{2} )2=(m\frac{35}{4} n)2=m\frac{70}{4} n=\frac{70}{4} mn[/tex]

The fraction can be expressed as:

\frac{70}{4}=\frac{68+2}{4}=\frac{68}{4}+\frac{2}{4}=17+\frac{1}{2}=17\frac{1}{2}

The expression can be simplified as [tex]17\frac{1}{2}[/tex]m·n
