1. Step-by-step explanation:

   [tex] {27x}^{3} + {8y}^{3} + 3 \times 3x \times 2y \\ (3x + 2y) \\ using \: {(a + b)}^{3} = {a}^{3} + {b}^{3} \\ + 3ab(a + b) \\ 27 {x}^{3} +8 {y}^{3} + 18xy(3x + 2y) \\ 27 {x}^{3} + {8y}^{3} + 54 {x}^{2}y + 36x {y}^{2} [/tex]

2. Answer: 27x³+8y³+ 54x²y + 36xy²

   Step-by-step explanation:

   ( 3x + 2y ) ³

   → (3x)³+(2y)³ + 3*3x*2y(3x + 2y)

   → 27x³+ 8y³ + 18xy( 3x + 2y)

   → 27x³+8y³+ 54x²y + 36xy²

   FORMULA USED :

   → (a+b)³ = a³+b³+3ab(a+b)

   Now make me BRAINLIST .
