Answer 1

Explicación paso a paso:

Formula de binomio al  cuadrado:

(a ± b)² = a² ± 2ab + b²

Resolvamos:

3)

(3x²+7z⁴)² = (3x²)² + 2(3x²)(7z⁴) + (7z⁴)²

(3x²+7z⁴)² = 9x⁴+42x²z⁴+49z⁸

4)

(12-10a⁸)² = (12)² - 2(12)(10a⁸) + (10a⁸)²

(12-10a⁸)² = 144 - 240a⁸ + 100a¹⁶

5)

(4x⁷+2y²)² = (4x⁷)² + 2(4x⁷)(2y²) + (2y²)²

(4x⁷+2y²)² = 16x¹⁴ + 16x⁷y² + 4y⁴

6)

(c⁵d⁶-6f¹¹)² = (c⁵d⁶)² - 2(c⁵d⁶)(6f¹¹) + (6f¹¹)²

(c⁵d⁶-6f¹¹)² = c¹⁰d¹² - 12c⁵d⁶f¹¹ + 36f²²
