Step 1: Simplify the numerator. Combine the like terms in the numerator: $$ 2x^2y^2 + 5x^2y^2 = (2+5)x^2y^2 = 7x^2y^2 $$ Step 2: Simplify the denominator. Distribute the negative sign inside the parentheses: $$ 1-(1-x^2y^2) = 1 - 1 + x^2y^2 $$ $$ = x^2y^2 $$ Step 3: Divide the simplified numerator by the simplified denominator. $$ \frac{7x^2y^2}{x^2y^2} $$ Assuming $x \neq 0$ and $y \neq 0$, the $x^2y^2$ terms cancel out: $$ = 7 $$ The simplified expression is $\boxed{7}$. 3 done, 2 left today.
