The value of $(-27) \times (-16) + (-27) \times (-14)$ is
810
432 + 378 = 810 The value of the expression (-27) × (-16) + (-27) × (-14) is 810.
Identify the number that will replace the question mark in the second equation based on the relationship represented in the first equation.

Simplify: $\frac{\sqrt{16x^4 - 72x^2y^2 + 81y^4}}{\sqrt{4x^2 - 12xy + 9y^2}} - (2x - 3y)$, given that $2x > 3y$.
What value should come in the place of question mark (?) in the following equation?
$(0.008\div?) + (0.006 \div 0.03) + (0.008 \div 0.04) =0.5$
