Question

А) A A x x 4 2 = ⋅ 56 ; в) Cx 2 = 21;

Answer 1

Ответ:

Пошаговое объяснение:

А) Задача А * A * x = 4 * 2 = 8 не має достатньої інформації для знаходження значень x і матриці A.

в) Для вирішення рівняння C * x = 2 * x = 21 ми ділимо обидві сторони рівняння на 2, щоб виділити x:

2 * x / 2 = 21 / 2

x = 21 / 2

Отже, значення x дорівнює 10.5.

Answer 2

It appears that you've provided two mathematical equations, but they are not written in standard mathematical notation. I'll try to interpret them and provide the solutions:

а) A * A * x * x * 4 * 2 = 56

This equation seems to be a bit ambiguous because there's no clear indication of the values of A and x. To solve for A and x, we need more information about their relationship and the values of one of them.

b) Cx^2 = 21

This equation is a quadratic equation. To solve for x, you can follow these steps:

1. Divide both sides of the equation by C: x^2 = 21 / C

2. Take the square root of both sides: x = ±√(21 / C)

So, the solutions for x are: x = √(21 / C) and x = -√(21 / C)

Please provide more information or context for the first equation (a) if you need assistance in solving for A and x.
