Question

If x3 + 27xy2 = 27y3 + 9x2y then x:y is​

Answer 1

$3 :1$

Step-by-step explanation:

$Given, \: \: x³+27xy²=27y³+9x²y \\ = > \: \: x³+27xy² - 27y³ - 9x²y = 0 \\ = > \: \: x³ -9x²y +27xy² - 27y³ = 0 \\ = > \: \: (x)^{3} - 3 \times {x}^{2} \times3 y + 3 \times x \times (3y)^{2} - (3y)^{3} = 0 \\ = > \: \: (x - 3y)^{3} = 0 \\ = > \: \: x - 3y = 0 \\ = > \: \: x = 3y \\ = > \: \: \frac{x}{y} = 3 \\ so, \: \: \: x : y = 3 :1$
