Answer 1

Answer:

$8x^3 + 27y^3 + 36x^2y + 54 xy^2$

Step-by-step explanation:

By using the formula:

$(a+b)^3 = a^3 + b^3 + 3ab (a + b)$

a = 2x ; b = 3y

$(2x + 3y)^3 = (2x)^3 + (3y)^3 + (3 * 2x * 3y)(2x + 3y)\\(2x + 3y)^3 = 8x^3 + 27y^3 + 18xy (2x + 3y)\\(2x + 3y)^3 = 8x^3 + 27y^3 + 36x^2y + 54 xy^2$
