Step-by-step explanation:
(a+b)³ = (a+b)(a²+2ab+b²)
=> (4x + 6y)³ = (4x+6y) ( 16x² + 2(24xy) + 36y²)
= 4x( 16x² + 48xy +36y²) + 6y( 16x² + 48xy +36y²)
= 64x³+192x²y+ 144xy²+ 96x²y + 288xy² + 216y³
= 64x³+288x²y + 432xy²+ 216y³

Answer: please mark me as brainliest
Step-by-step explanation:
(4x+6y)³
= (4x)³ + (6y)³ + 3(4x)²6y+16x(6y)²
= 64x³ + 216y³ + 3×16x² × 6y + 3×4x×36y²
Final answer = 64x³ + 216y³ + 576 x²y + 432xy²
