Answer 2

Answer:

2m²-3n² = 23

(2m)² - (3n)² = 19

Step-by-step explanation:

There is not much clarity in the question. we can assume the question be asked to 2 different ways.

1). 2m²-3n²

   = 2*(5)² - 3*(3)²

   = 2*25 - 3*9

   = 50-27

   = 23

2) (2m)² - (3n)²

    = (2*5)² - (3*3)²

    = 10²-9²

    = 100-81

    = 19
