1. Answer:

   In the given algebraic expression −2m

   3

   −3n

   2

   +5m

   2

   n, we substitute m=3 and n=2 as shown below:

   −2m

   3

   −3n

   2

   +5m

   2

   n

   =−2(3)

   3

   −3(2)

   2

   +5(3)

   2

   (2)

   =−(2×27)−(3×4)+(5×9×2)

   =−54−12+90

   =−66+90

   =24

   Hence, −2m

   3

   −3n

   2

   +5m

   2

   n=24.
