Answer 1

Ответ:

1) 49-(m-3)=49-m+3=52-m

Answer 2

Let's solve each of the given equations step by step:

1. 49 - (m - 3) = 49 - m + 3 = 52 - m

So, the solution is 52 - m.

2. (3x + 1)² - (4x + 3)² = (9x² + 6x + 1) - (16x² + 24x + 9) = 9x² + 6x + 1 - 16x² - 24x - 9 = -7x² - 18x - 8

So, the solution is -7x² - 18x - 8.

3. (6y - 7)² - (9y + 4)² = (36y² - 84y + 49) - (81y² + 72y + 16) = 36y² - 84y + 49 - 81y² - 72y - 16 = -45y² - 156y + 33

So, the solution is -45y² - 156y + 33.

4. 216x² - y³ = 0

There is no way to simplify this equation further without additional information. It is an equation in two variables, and we need more information to solve for the variables.

5. 512³ - 125 = 134,456,576 - 125 = 134,456,451

So, the solution is 134,456,451.

Please note that equation 4) cannot be solved without more information, as it involves two variables (x and y) without any specific conditions or constraints.
