Answer 2

$( - {3b}^{2} - {c}^{3} {)}^{2} = - {9b}^{4} - 6 {b}^{4} {c}^{6} + {c}^{9} \\ ( {x}^{3} + \frac{1}{4} {xy}^{2} {)}^{2} = {x}^{9} + \frac{1}{8} {x}^{6} {y}^{4} + \frac{1}{16} {x}^{2} {y}^{4}$

Я сама эту тему недавно проходила.

Довольно лёгкая тема,если понять

Answer 3

Solving the Expression (х³ + ¼ + хy²)² + (-3b² - с³)²

To solve the given expression (х³ + ¼ + хy²)² + (-3b² - с³)², we can start by expanding and simplifying each part of the expression separately.

Expanding and Simplifying (х³ + ¼ + хy²)²

The expression (х³ + ¼ + хy²)² can be expanded using the formula (a + b)² = a² + 2ab + b².

Expanding (х³ + ¼ + хy²)²: (х³ + ¼ + хy²)² = (х³)² + 2 * (х³) * ¼ + (¼)² + 2 * (х³) * хy² + 2 * ¼ * хy² + (хy²)²

Simplifying the terms: (х³)² = х^6 2 * (х³) * ¼ = ½х^3 (¼)² = 1/16 2 * (х³) * хy² = 2х^3y² 2 * ¼ * хy² = ½xy² (хy²)² = x²y^4

Combining the simplified terms: (х³ + ¼ + хy²)² = х^6 + ½х^3 + 1/16 + 2х^3y² + ½xy² + x²y^4

Expanding and Simplifying (-3b² - с³)²

Similarly, we can expand and simplify the expression (-3b² - с³)².

Expanding (-3b² - с³)²: (-3b² - с³)² = (-3b²)² + 2 * (-3b²) * (-с³) + (-с³)²

Simplifying the terms: (-3b²)² = 9b^4 2 * (-3b²) * (-с³) = 6b²c³ (-с³)² = c^6

Combining the simplified terms: (-3b² - с³)² = 9b^4 + 6b²c³ + c^6

Putting It All Together

Now, we can add the simplified expressions together: (х³ + ¼ + хy²)² + (-3b² - с³)² = (х^6 + ½х^3 + 1/16 + 2х^3y² + ½xy² + x²y^4) + (9b^4 + 6b²c³ + c^6)

This is the detailed breakdown of the steps to solve the given expression. If you have any further questions or need additional assistance, feel free to ask!
