Answer:

[tex]9m^4 - 49n^6[/tex]

Step-by-step explanation:

Hello!

For an equation to be a Difference of Squares, the coefficient of the variables has to be Perfect Squares (product of a number squared) and the operation has to be a subtraction between the two terms.

The only option that meets the requirements is  [tex]9m^4 - 49n^6[/tex], as 9 and 49 are perfect squares.

In Option 1, 21 is not a perfect square.

In Option 3, 32 is not a perfect square.

In Option 4, 10 is not a perfect square.
