Question

вычислите:
(5*x^2*y^3*z^4):(3*x^2*y*z^2)^2

Answer 1

(5*x^2*y^3*z^4):(3*x^2*y*z^2)^2 = 5х²у³z⁴:9x⁴y²z⁴ = 5y:9x²

Answer 2

$\frac{5*x^2*y^3*z^4}{(3*x^2*y*z^2)^2 } = \frac{5*x^2*y^3*z^4}{3^2*x^4*y^2*z^4} =$

$= \frac{5}{9}* \frac{x^2}{x^4}* \frac{y^3}{y^2} * \frac{z^4}{z^4} =$

$= \frac{5}{9}* \frac{1}{x^{2}}* y * 1 = \frac{5y}{9x^{2}}$
