Question

ayudenmen a desarrollar estos ejercicios del cubo de un binomio primer ejercicio (3x²+2y⁴)³ El segundo ejercicio (⅔x³+¾y²)³

Answer 1

Formula: a³ + 3a²b + 3ab² + b³

(3x² + 2y⁴)³
(3x²)³ + 3(3x²)²(2y⁴) + 3(3x²)(2y⁴)² + (2y⁴)³
27x^6 + 3(9x⁴)(2y⁴) + 3(3x²)(4y^8) + 8y^12
R = 27x^6 + 54x⁴y⁴ + 36x²y^8 + 8y^12

(⅔x³ + ¾y²)³
(2/3x³)³ + 3(2/3x³)²(3/4y²) + 3(2/3x³)(3/4y²)² + (3/4y²)³
8/27x^9 + 3(4/9x^6)(3/4y²) + 3(2/3x³)(9/16y⁴) + 27/64y^6
8/27x^9 + x^6y² + 27/24x³y⁴ + 27/64^6
