Question

Calcule as equações (30xy)^4:(-4x^2)

Answer 1

$\frac{(30xy)^{4}}{-4x^{2}} \ \ \ \ \\\\\\ =\ \ \ \ \ \frac{30^{4}x^{4}y^{4}}{-4x^{2}} \ \\\\\\ \ =\ \ \ \frac{810\ 000x^{4}y^{4}}{-4x^{2}} \\\\\\=\ \ \ \frac{810\ 000y^{4}}{-4} . \frac{x^{4}}{x^{2}} \\\\\\=\ \ \ -202\ 500y^{4}.\ x^{4-2}\\\\\\=\boxed{\boxed{-\ 202\ 500x^{2}y^{4}}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ok$
